If you are looking for a unique and colorful addition to your aquarium, the clown triggerfish is a great choice. These fish are known for their vibrant patterns and playful personalities, making them a popular choice among hobbyists. However, before you bring one home, it is important to understand their specific care requirements.

Clown Triggerfish is a marine fish species that requires a minimum tank size of 300 gallons. They prefer a pH range of 8.1-8.4 and stable water conditions. They are carnivorous and should be fed a varied diet of meaty foods. Regular water changes and proper filtration are necessary for their well-being.

One of the key things to keep in mind when caring for clown triggerfish is their size. These fish can grow up to a foot long, so you will need a tank that is at least 150 gallons to accommodate them. Additionally, they are known for their aggressive behavior, so it is important to choose tankmates carefully and provide plenty of hiding spots and territory markers to reduce stress.

Another important aspect of caring for clown triggerfish is their diet. These fish are carnivorous and require a diet high in protein. This can include a variety of foods such as shrimp, krill, and squid. It is also important to avoid overfeeding, as these fish are prone to obesity and related health issues.

Species Summary

If you’re considering adding a clown triggerfish to your aquarium, it’s important to know everything you can about this unique species.

Below, we’ll cover the key points you need to know about clown triggerfish care.


The clown triggerfish (Balistoides conspicillum) is a saltwater fish that’s native to the Indo-Pacific region.

They can be found in the waters around Australia, Indonesia, and the Philippines, among other locations.


With proper care, clown triggerfish can live for up to 20 years in captivity.

However, their lifespan can be significantly shorter if they’re not kept in ideal conditions.


Clown triggerfish are known for their striking appearance. They have a bright yellow body with black and white stripes, and their fins are outlined in blue.

They also have a distinctive mouth that protrudes from their face, which they use to crush the shells of their prey.


Clown triggerfish can grow up to 1.5 feet in length, so they need a large aquarium to thrive.

They should be kept in tanks that are at least 200 gallons in size.

Growth Rate

Clown triggerfish grow relatively quickly, especially when they’re young.

However, their growth rate will slow down as they get older.

Behavior & Temperament

Clown triggerfish are known for their aggressive behavior, so they’re not recommended for beginner aquarists. They can be territorial and may attack other fish in the tank.

However, they can be kept with other large, aggressive fish as long as there’s enough space in the aquarium.

Male vs Female

It can be difficult to tell male and female clown triggerfish apart.

However, females tend to be slightly smaller and have a rounder belly than males.

When I first added a clown triggerfish to my aquarium, I was amazed by its striking appearance.

However, I quickly learned that these fish require a lot of care and attention to thrive.

By following the tips outlined in this article, you can ensure that your clown triggerfish stays healthy and happy in your aquarium.

Tank Setup

Setting up a proper tank for your clown triggerfish is crucial to their health and well-being.

Here are the key factors to consider when creating the ideal environment for your fish.

Tank Size

The minimum tank size for a clown triggerfish is 100 gallons. However, it’s recommended to provide more space if possible.

Larger tanks provide more swimming room and allow for better water quality. Remember, clown triggerfish are active swimmers and need plenty of room to move around.


Clown triggerfish prefer low to moderate lighting. Avoid bright lights as they can cause stress and even damage to their eyes.

Consider using LED lights that mimic natural sunlight to provide a comfortable environment for your fish.

Filtration & Aeration

Adequate filtration and aeration are essential for maintaining a healthy tank. A good filter will remove waste and debris from the water, while aeration will increase oxygen levels.

A protein skimmer is also recommended to remove excess waste and prevent harmful toxins from building up in the water.


Clown triggerfish require a consistent water temperature between 75-82°F.

Use a reliable heater to maintain the desired temperature and ensure your fish are comfortable.


Choose a substrate that is easy to clean and maintain.

Sand or crushed coral are good options as they mimic the natural environment of the clown triggerfish. Avoid sharp or rough substrates that can damage your fish.


Add rocks, caves, and other structures to provide hiding places for your clown triggerfish.

They enjoy exploring their surroundings and having a place to retreat to when feeling threatened or stressed.


Clown triggerfish do not require live plants in their tank, but you can add artificial plants for decoration.

Just make sure they are made of safe materials and won’t harm your fish.

When setting up your clown triggerfish tank, keep in mind that each fish has its own unique personality and preferences.

Pay attention to how your fish responds to different elements in the tank and adjust accordingly. With the right setup, your clown triggerfish will thrive and provide years of enjoyment.

Personally, I found that adding a few small caves and a variety of artificial plants made my clown triggerfish feel more comfortable and at home in the tank. It was fascinating to watch them explore their new environment and find their favorite hiding spots.

Water Quality

Ensuring proper water quality is essential for the health and well-being of your clown triggerfish. Here are some key factors to consider:

Water Temperature

The ideal temperature range for clown triggerfish is between 75-82°F (24-28°C). Consistency is key, so make sure to monitor the temperature regularly and adjust as necessary.

Rapid temperature changes can be stressful for your fish and may impact their health.

Water pH

Clown triggerfish prefer a pH range between 8.1-8.4. Keeping the pH stable is important, as fluctuations can cause stress and health issues.

Regular water testing can help you maintain the appropriate pH levels.

Water Hardness

Clown triggerfish thrive in water that is moderately hard, with a range of 8-12 dKH.

Water hardness can impact the health and growth of your fish, so it’s important to monitor and adjust as needed.

Water Changes

Regular water changes are crucial for maintaining water quality.

Aim for a 10-20% water change every 2-4 weeks, depending on the size of your tank and the number of fish.

This helps remove excess nutrients and maintain a healthy environment for your clown triggerfish.

Personally, I have found that maintaining proper water quality is one of the most important factors in keeping my clown triggerfish healthy and happy.

By monitoring temperature, pH, hardness, and performing regular water changes, you can ensure a thriving environment for your fish.

Tank Maintenance

Keeping your clown triggerfish happy and healthy requires regular tank maintenance. Here are some tips to help you keep your tank in top condition:

First, you need to make sure that you have the right equipment. You will need a good quality filter, a protein skimmer, and a heater. Make sure that your filter is large enough to handle the size of your tank and that it is cleaned regularly.

Your protein skimmer will help remove waste from the water, and your heater will keep the temperature stable.

Next, you will need to perform regular water changes. This will help remove any excess nutrients and waste from the water.

You should aim to change around 10-20% of the water in your tank every two weeks. Be sure to use a good quality salt mix to prepare your new water.

You should also test your water regularly to make sure that the levels of ammonia, nitrite, and nitrate are within acceptable limits.

You can use a test kit to do this. If you notice any problems, you may need to perform additional water changes or adjust the levels using additives.

Finally, you should keep an eye on the cleanliness of your tank. Make sure that you remove any uneaten food, dead fish, or other waste promptly. You can also use a gravel vacuum to clean the substrate of your tank.

This will help prevent the buildup of harmful bacteria and other organisms. I’ve found that regular maintenance is key to keeping my clown triggerfish happy and healthy. By following these tips, you can ensure that your fish has a clean and healthy environment to live in.

Tank Mates

Compatible Fish Species

If you’re considering adding clown triggerfish to your aquarium, it’s important to choose compatible tank mates.

Clown triggerfish are known to be aggressive towards other fish, so it’s best to select species that can hold their own. Some compatible species include:

  • Tangs
  • Butterflyfish
  • Wrasse
  • Surgeonfish
  • Groupers

Incompatible Fish Species

Clown triggerfish are not suitable tank mates for all fish species. Avoid keeping them with small, peaceful fish that may be intimidated or bullied. Incompatible species include:

  • Angelfish
  • Gobies
  • Blennies
  • Damsels

Can You Put 2 Trigger Fish Together?

While it’s possible to keep two clown triggerfish together, it’s not recommended. These fish are territorial and may become aggressive towards each other, especially if they are of the same sex.

If you do decide to keep two clown triggerfish together, make sure your tank is large enough to accommodate both fish and provide plenty of hiding places to reduce aggression.

I’ve found that my clown triggerfish has been most successful in a tank with a few other larger fish. I’ve had success keeping him with a group of tangs and a grouper.

However, I made sure to provide plenty of hiding spots and keep a close eye on any signs of aggression.

Remember, every fish is different, and it’s important to observe your fish’s behavior and make adjustments as necessary to ensure a happy and healthy aquarium.


Clown triggerfish are carnivorous and require a diet that is high in protein. A well-balanced diet is essential for their overall health and vitality.

In this section, we will cover what to feed your clown triggerfish, how often to feed them, and some tips to keep them healthy and happy.

What To Feed

Clown triggerfish require a diet that is high in protein, and they prefer live foods. Some great options for their diet include krill, shrimp, squid, and small fish.

You can also feed them frozen foods, such as mysis shrimp, brine shrimp, and krill. It is important to vary their diet to ensure they are receiving all the necessary nutrients.


You should feed your clown triggerfish two to three times a day, but be careful not to overfeed them. Overfeeding can lead to health problems and can also pollute the water.

A good rule of thumb is to feed them only as much as they can consume in two to three minutes. If there is any uneaten food, remove it from the tank.


When feeding your clown triggerfish, it is important to take some precautions to ensure their safety. They have strong jaws and teeth, so be careful when feeding them with your hands.

You can use a feeding stick to avoid getting bitten. Also, make sure to soak any frozen food in tank water before feeding to avoid digestive problems.

Finally, consider adding some live rock to their tank. This will provide them with natural food sources, such as crustaceans and small invertebrates.

Personally, I have found that my clown triggerfish loves frozen krill. I usually feed him a small amount in the morning and then again in the evening.

I have also noticed that he enjoys chasing after live brine shrimp, which I occasionally add to his diet as a treat. Remember to keep their diet varied and to monitor their eating habits to ensure they are healthy and happy.

Common Diseases


Clown triggerfish are generally healthy fish, but they are susceptible to a few common diseases. One of the most common diseases is Ich, which is caused by a parasite.

Other diseases that can affect clown triggerfish include fin rot, velvet disease, and bacterial infections.


If your clown triggerfish is sick, you may notice a few symptoms. Ich will cause white spots to appear on the fish’s body and fins.

Fin rot will cause the fins to become frayed and discolored. Velvet disease will cause a gold or rust-colored dust to appear on the fish’s body.

Bacterial infections can cause the fish to become lethargic and lose its appetite.


If you notice that your clown triggerfish is sick, you should isolate the fish in a quarantine tank. You can treat Ich with medication that is available at your local pet store.

Fin rot can be treated by improving water quality and adding medication to the water. Velvet disease can be treated with medication that is available at your local pet store.

Bacterial infections can be treated with antibiotics that are available at your local pet store.


The best way to prevent diseases in your clown triggerfish is to maintain good water quality. You should perform regular water changes and use a high-quality filter.

You should also avoid overfeeding your fish, as this can lead to poor water quality.

Additionally, you should avoid introducing new fish to your aquarium without quarantining them first.

I have personally dealt with Ich in my clown triggerfish, and it was a stressful experience.

However, with the right medication and care, my fish made a full recovery. Remember to always keep an eye on your fish and take action if you notice any signs of illness.

Signs Your Clown Triggerfish is Sick

If you’re a new owner of a clown triggerfish, it’s important to know the signs of a sick fish. Even if you’re a seasoned owner, it’s always good to refresh your memory. Here are some signs that your clown triggerfish may be sick:

  1. Loss of appetite: If your clown triggerfish is not eating, it may be a sign of illness. Try offering different types of food to see if it will eat.
  2. Behavior changes: If your clown triggerfish is suddenly hiding or swimming erratically, it may be a sign of illness.
  3. Visible signs: Look for any physical signs such as discoloration, spots, or sores. These can be signs of bacterial or fungal infections.

It’s important to note that some of these signs may not always indicate illness.

For example, clown triggerfish are known to be aggressive and may hide or swim erratically when they feel threatened.

However, if you notice any of these signs, it’s best to monitor your fish closely and consider consulting with a veterinarian who specializes in fish care.

Personally, I once noticed that my clown triggerfish was not eating as much as usual and was swimming more slowly than usual. I became concerned and consulted with a veterinarian who recommended a change in diet and some medication. After following the veterinarian’s advice, my fish made a full recovery.


Breeding clown triggerfish can be challenging, but it can also be very rewarding. Here are the key things you need to know about breeding clown triggerfish.

Breeding Setup

To breed clown triggerfish, you will need a large aquarium with plenty of hiding places. A 100-gallon tank with plenty of live rock and a sandy substrate is ideal.

You will also need a male and female clown triggerfish. It is important to choose healthy fish that are free from disease.

How To Breed

Breeding clown triggerfish can be difficult, but it is possible with the right conditions. The first step is to introduce the male and female to the breeding tank.

The male will start to court the female by swimming around her and showing off his colors. Once the female is ready to mate, she will lay her eggs on a flat surface, such as a rock or the aquarium glass.

After the eggs are laid, the male will fertilize them. The eggs will hatch in about four days, and the fry will become free-swimming in about a week.

It is important to remove the fry from the breeding tank once they are free-swimming, as the adult fish may eat them.


After the fry are removed from the breeding tank, they will need to be fed several times a day with small amounts of food.

Baby brine shrimp and crushed flake food are good options. It is important to keep the water in the fry tank clean and well-oxygenated. It is also important to monitor the health of the fry closely.

If you notice any signs of disease or stress, you should take action immediately to prevent the spread of illness.

I have found that breeding clown triggerfish can be a challenging but rewarding experience. It takes patience and dedication, but the end result is worth it. Good luck with your breeding endeavors!
