Beautiful fish with tons of personality but do become a dominant fish if not challenged. Like most larger wrasse fish, they swim large distances in the wild & require a large tank with a very strong current of water, kind of like a distance runner with infinite endurance, giving them a huge appetite. If not fed multiple times a day, they will go out for a hunt & begin to show aggression towards other tank mates, especially towards inverts that the wrasse will look at as food. If it is well fed with the proper diet, it’s aggression can be subdued. It also helps if the aquascape is setup like an obstacle course, where it can swim in & out of structures with ease. That’s been my experience with banana wrasses.
I had one that eventually figured out how to catch my attention when it wanted food. It would lay on the sand bed in front of the tank & play dead in order to get food, it would do this at least 3 times a day when I was home all day. The rest of the day, it would swim laps none stop. I eventually had to give him away because it grew to roughly 7” & was to large for my tank. One of the best wrasses I’ve owned. Hope it helps & good luck.
