The canary blenny adds a bright yellow splash to my tank. I’ve been keeping it for three months and it’s active and healthy. I provide frozen mysis twice a week and it enjoys the rocks in the tank. Very easy to care for once the water parameters are stable.

Beautiful fish with a lovely color. I noticed males grow larger than females. I keep it in a 55-gallon tank with plenty of rock structures. Feeding it mysis works well. It’s not aggressive and blends well with other community fish.

Great addition to a tropical aquarium. The fish stays active and shows good color even after a few weeks. I maintain pH between 8.2 and 8.4 and specific gravity around 1.023. Feeding with chopped prawn works well and it seems to thrive.
