Bought this wrasse for my 75-gallon tank. It’s active and curious, but I had to keep it separate from smaller fish. It’s not reef-safe, which is clearly stated. Good for experienced aquarists who can manage aggression.

The wrasse arrived healthy and seems to be adjusting well. I’ve noticed it’s quite territorial, so I’ve added a few larger fish to help deter it. Not for beginners, but it’s a good addition to a well-established tank.
Lillian Miller –
This tiny wrasse is a great fit for my intermediate tank. It’s active and adds visual interest. Just make sure to provide plenty of hiding spots and avoid keeping it with small or shy species.
