Bought this wrasse for my 80-gallon tank. It’s active and territorial, which is expected given its aggressive disposition. I’ve had to keep it away from other fish, but it’s healthy and eats well. Good for experienced aquarists who can manage its behavior.

The wrasse arrived healthy and fits well in my tank. I noticed it’s quite active and needs a lot of space. I’m not sure if it’s compatible with my small group of tangs, but it’s not damaging anything yet.

This wrasse has been thriving in my 75-gallon tank. It’s a bit aggressive, but I’ve arranged the tank layout to give it room. Feeds well on frozen foods and shows no signs of stress.
