The Saddle Wrasse arrived healthy and active. After setting up a 120-gallon tank with proper hiding spots and rock structure, it adapted well. It’s aggressive but not overly so when given space. I’ve noticed it patrols the edges and defends its territory. Good for experienced reef keepers who can manage its behavior.

I added this wrasse to my 100-gallon tank after reading the care notes. It’s active and curious, and it seems to coexist with some corals, though I’ve seen it nipping at smaller polyps. I keep an eye on it and provide plenty of live rock for shelter.

The fish is aggressive and not suitable for a small tank. I had to upgrade to a 120-gallon system. It’s active and interesting, but I’d recommend only for intermediate to advanced aquarists with a well-established reef setup.
