Added a school of Yellow Edge Chromis to my 20-gallon tank. They’ve been active and colorful since day one. The yellow fin edges stand out beautifully against the blue body. Easy to care for and don’t stress other fish. Great for a beginner reef setup.

I bought five of these fish for my reef tank. They swim together in a tight school and add a lot of visual interest. Feeding is simple—just a few brine shrimp each week. No issues with compatibility or aggression so far.

The fish are very active and colorful. I noticed slight territorial behavior between males during feeding, but it didn’t affect the group. They adapted well to the tank after a week. Good value for the vibrant appearance.
