So far, so good. I have two cleaner shrimp, one coral banded shrimp, three emerald crabs, one porcelain crab, and a tone of scarlet crabs and snails. All the wrasse does is pick the algae off the rocks and eat what I feed, SO FAR!!!!. I will continue to keep a close eye on it. One of my cleaners molted and he didn't touch the molt.
I have very active cleaner shrimp and they jump on every fish that swims by. I am just waiting for one to jump on the wrasse and see what happens. Like I said, So far, So good. I only paid 20.00 for it and if I have to give it away, no big deal. My buddy has a 135 FO
