Added a school of Green Chromis to my 55-gallon reef tank. They are active and colorful, and have not shown any aggression toward other fish. The shimmering green hue is very eye-catching under the LED lights. A great addition for a peaceful, lively display.

I was worried about introducing a damselfish to my tank, but the Green Chromis are calm and don’t bother my corals or other fish. They swim in tight groups and create a nice visual flow. Easy to care for and very attractive.

After a few weeks, the fish have fully settled into the tank and are swimming together in a coordinated school. Their color changes slightly with the lighting, which adds depth to the tank’s appearance. Highly recommend for reef enthusiasts.
