The Yellow Banana Wrasse is a beautiful addition to my 60-gallon reef tank. It’s active and colorful, and it doesn’t seem to bother the corals. I’ve had it for three months and it’s still showing great energy. A great choice for intermediate keepers who want vibrant movement.

It’s a striking fish with bright yellow coloring. I noticed it occasionally nudges some soft corals, so I’ve added a bit of space around them. Overall, it’s peaceful and adds a lot of visual interest.
