Diane Forsyth –
Got the Rainbow Wrasse for my 75-gallon tank. It’s active and colorful, but I had to remove a few small fish after a few weeks due to aggression. The fish is vibrant and adds a lot of visual interest. Needs a strong, stable environment and regular monitoring.
Neil Kerr –
It’s a striking fish with bright colors. I expected more aggression, but it’s manageable with proper tank mates. I removed a small shrimp after a few days. Not ideal for small tanks or with shy species.

The fish arrived healthy and has been active since setup. I’ve kept it with a few larger, robust corals and it hasn’t shown signs of attacking them. It’s a great addition to a well-established reef tank.
