The Golden Tiger Blenny (Ecsenius sp.) is a beautiful and interesting saltwater fish often kept in marine aquariums. These blennies are known for their vibrant colors and unique behavior, including perching on rocks and poking their heads out from crevices. Here's a care guide to help you maintain a Golden Tiger Blenny in your saltwater aquarium.

Tank Size

A minimum tank size of 30 gallons (around 113 liters) is suitable for a single Golden Tiger Blenny. Larger tanks offer more space and stability for your fish.

Water Quality

Maintain stable water parameters, including a temperature range of 72-78°F (22-26°C) and a specific gravity of around 1.025. Regularly test and adjust pH, ammonia, nitrites, and nitrates to ensure optimal water quality.


Use an efficient filtration system, such as a protein skimmer or a canister filter, to remove waste and maintain water clarity. Live rock can assist in biological filtration and create hiding spots for your Golden Tiger Blenny.


Golden Tiger Blennies are herbivorous, primarily grazing on algae. Offer a diet that includes marine algae, seaweed, and other plant-based foods. Supplement their diet with high-quality marine pellets or flakes designed for herbivorous fish.

Feeding Schedule

Feed your Golden Tiger Blenny multiple times a day, as they have small stomachs and require frequent grazing.


Golden Tiger Blennies are generally peaceful and can coexist with other peaceful reef fish. Ensure that tankmates are compatible with Blennies and won't harass or outcompete them for food.

Hiding Spots

Provide hiding spots using live rock, caves, and crevices to make your Golden Tiger Blenny feel secure. They often dart into hiding when they feel threatened or stressed.

Water Flow and Lighting

Moderate water flow is suitable for these blennies. Lighting requirements will depend on your overall aquarium setup, but they don't have specific lighting needs.


Quarantine new fish before introducing them to your main tank to prevent the spread of disease.


Regularly monitor your fish for any signs of stress, disease, or aggression, and take appropriate actions if any issues arise.

Golden Tiger Blennies are fascinating additions to a marine aquarium. They contribute to algae control and exhibit captivating behaviors. To ensure their health and well-being, provide them with a suitable habitat, maintain water quality, and offer a balanced diet. As with any marine species, maintaining proper water quality is crucial to keeping them healthy and happy.
