I added the Six-Lined Soapfish to my 100-gallon reef tank and it has been thriving. The fish is active and colorful, and it doesn’t seem to harm the corals. Easy to care for as a beginner-level species. I’m happy with the purchase.

The fish arrived healthy and has adapted well to the tank. It’s semi-aggressive but not overly so. I appreciate the clear care instructions and the reef compatibility note. A good choice for a new reef keeper.
