Stephen Parr –
Added a group of Agile Chromis to my 30-gallon reef tank. They are active and colorful, and they don’t bother the corals. Easy to care for and great for a beginner aquarist.
Joan Coleman –
The fish are lively and add movement to the tank. I kept them with other peaceful species and they coexist well. Only a bit of aggression when feeding, but manageable.

Perfect for a small reef setup. They stay healthy and active even after a few weeks. No issues with coral or invertebrates. Highly recommend for beginners.
