Blue Damselfish prefer a well-lit aquarium with plenty of hiding spots. These can be provided through live rocks or coral. They thrive in water temperatures between 72-78°F.
Behavior
Blue Damselfish are known to be territorial and can become aggressive, especially in smaller tanks. They are also active swimmers and are known to be quite hardy, making them suitable for beginner aquarists.

After 3 weeks, I managed to kill it, but my ammonia was too high for too long. Totally my fault. She ate almost out of my hand. She was pretty active, but not quite as much as clowns. She hid more when she started suffering.

Bullies other fish and bites when doing maintenance

This fish is always swimming around and I haven’t had any issues with it being aggressive. It is in a 125 gallon so idk if that’s what helps with its temperament but it has been a model citizen fish.

They can pick on smaller tank mates, but usually it’s not an extended problem. They have really great color and look beautiful under all types of lights
