Although not critical, live plants or quality artificial plants can provide additional hiding places and encourage natural behavior in Red Scooter Blennies. Hardy options like Java Fern or Anubias will work well.

Water Quality

Water Temperature

Maintaining a stable water temperature is crucial for the health of your Red Scooter Blenny. I’ve found that 72-78°F (22-26°C) is the optimal range for them. Consistency is key, so it’s important to invest in a reliable heater and thermometer to monitor the temperature.

Water pH

Red Scooter Blennies prefer slightly alkaline water conditions. Aim for a pH level between 8.1 and 8.4. Regularly test and adjust the pH to prevent stress on your fish. Buffer solutions can help maintain ideal pH levels.

Water Hardness

When it comes to water hardness, these blennies thrive in water with a hardness between 8 and 12 dKH (degrees of carbonate hardness). Monitoring the hardness ensures a stable and healthy environment. Some ways to adjust water hardness include adding crushed coral or using commercial additives.

Water Changes

Regular water changes are essential for maintaining a healthy environment for your Red Scooter Blenny. I usually perform 10-15% water changes weekly. This helps keep water parameters stable and removes waste that can accumulate over time. Remember to use a quality water conditioner when adding new water to the tank to eliminate harmful chemicals.

Tank Maintenance

Proper tank maintenance is crucial for the well-being of a Red Scooter Blenny. It starts with a well-established aquarium of at least 30 gallons, filled with live rock to provide hiding spots and grazing surfaces.

A good water filtration system is necessary to maintain high water quality. Perform regular water tests to ensure levels of ammonia, nitrites, and nitrates are kept in check. Additionally, provide adequate water flow to mimic the Blenny’s natural habitat.

When I first started keeping Red Scooter Blennies, I noticed they had a preference for clean, spacious environments. This encouraged me to keep up with regular partial water changes (20-30% every 2-4 weeks) to reduce harmful elements and replace trace minerals.

It’s essential to maintain a stable water temperature between 72-78°F, and ensure a salinity of 1.020-1.025 specific gravity. Accurately monitor these parameters with a reliable heater and a high-quality refractometer.

Feeding the Blenny a varied diet will promote optimal health. Include a mix of prepared foods and live or frozen options, such as copepods and mysis shrimp. Observe their feeding behaviors to ensure they are getting enough nutrients.

Managing the algae growth in the tank can directly benefit the Blenny’s well-being.

Tank Mates

Compatible Fish Species

In my experience, Red Scooter Blennies get along well with many peaceful fish species. Here are a few suitable tank mates:

  • Clownfish: These colorful and social fish coexist harmoniously with Red Scooter Blennies.
  • Gobies: Sharing a similar size and temperament, Gobies make good companions for Red Scooter Blennies.
  • Firefish: Known for their passive nature, Firefish are a compatible match as well.

Incompatible Fish Species

On the other hand, it is essential to avoid aggressive or predatory fish species that might view Red Scooter Blennies as prey. Incompatible species include:

  • Lionfish: These highly predatory fish are not a good match, as they may try to eat Red Scooter Blennies.
  • Triggerfish: Known for their territorial nature, Triggerfish might attack or harass Red Scooter Blennies.
  • Dottybacks: Although small, Dottybacks can be quite aggressive and may not tolerate the scooter blennies.

In my own experience, I once mistakenly placed a Red Scooter Blenny with a large Angelfish. Unfortunately, the Angelfish became territorial and chased the Blenny. Since then, I have learned that compatibility is crucial for a harmonious and healthy aquarium environment.


What To Feed

Red Scooter Blennies are carnivorous and require a diet rich in meaty foods. As an experienced aquarist, I have found that a varied diet of copepods, amphipods, and mysis shrimp is most suitable for them. These foods provide the essential nutrients and support the blennies’ overall health.

Feeding Frequency

Feeding your Red Scooter Blenny 2-3 times daily is a good practice. I remember when I started keeping them, I quickly realized that their small size and high metabolism demanded this frequency to ensure their well-being.


  1. Live foods like copepods and amphipods are great for encouraging natural feeding behaviors in Red Scooter Blennies. I once seeded my tank with live copepods and observed my blennies thriving with increased activity levels.
  2. Frozen mysis shrimp can also be a valuable addition to their diet. However, always thaw the frozen food before feeding it to your blennies.
  3. Consider using feeding aids, such as a feeding pipette, to deliver food directly to your Red Scooter Blennies. This reduces waste and ensures your blennies get the nourishment they need.

Remember, a varied diet and proper feeding schedule contribute significantly to the overall health and happiness of your Red Scooter Blennies.

Common Diseases


One common disease that affects Red Scooter Blennies is Ich (Ichthyophthirius multifiliis). This is a parasitic infection that can rapidly spread in a tank. Another less common but severe disease is Marine Velvet (Amyloodinium ocellatum), a parasitic infection similar to Ich but more aggressive.


When my Red Scooter Blenny had Ich, I noticed small white spots on its body and fins, while the fish was scratching itself on rocks and seemed more lethargic. In the case of Marine Velvet, the fish will display a gold or velvet-like dusting on its body, rapid breathing, and loss of appetite.


To treat Ich, I raised the temperature of the tank and removed the fish into a quarantine tank with a copper-based medication for about two weeks. As for Marine Velvet, treatment is challenging, and I had to use a stronger copper-based medication in a separate quarantine tank for more extended periods, sometimes up to a month.


  • Regular water testing to ensure proper water parameters
  • Quarantine new fish before adding them to the main tank
  • Monitoring fish for any signs of distress or illness
  • Providing a balanced diet and clean environment

By following these steps, the chances of your Red Scooter Blenny contracting common diseases can be significantly reduced, ensuring a healthy and vibrant fish.

Signs of a Healthy Fish

A healthy Red Scooter Blenny will display vibrant coloration and clear, bright eyes. They should be actively swimming around the tank foraging for food. I remember when I first got my Red Scooter Blenny, I was fascinated by its active behavior and striking colors.

These fish should also have a well-rounded body, indicating they are receiving proper nourishment. Keep an eye on their weight, as a thin or emaciated fish might be a sign of an underlying health issue.

Moreover, their fins should be free from any tears, nicks, or unusual growths. The gills should be clean, with no sign of inflammation or discoloration.

Monitoring the overall behavior of your Red Scooter Blenny can also give you an idea about their health status. For instance, they should not display any signs of aggression toward tank mates or show any signs of distress, such as rapid breathing or excessive hiding.

Remember, a happy and healthy Red Scooter Blenny will have all these characteristics – and having one as a pet can be a truly rewarding experience.
