My tangs are eating my wellso brain

[saltfishguy18]

Need some ideas on how to stop my purple tang and blue hippo tang from eating my wellso brain. They started picking it about 6 weeks ago. I loaned it to my buddy for 2 weeks and it fully healed and I put it back in my tank the day before Christmas Eve. I caught both tangs picking at it on Christmas Eve again so I put it in my sump until I can figure out what to do with it. I can't re arrange my rocks because everything is in a place for a purpose and if I pull one out all of it comes down lol. I have the wellso on the sand right now. I also have a feeling my tangs are picking at my trachy too, can't tell yet because there are no bite marks but it's not opening like usual anymore. Only thing I can think of is feeding more to stop them from picking. Thing is my fish are not skinny either, they are very fat. I feed a variety of frozen and pellet every day. Any suggestions would be helpful. My buddy said he will buy my wellso if I can't keep him but he is an amazing piece when healthy and one of the originals so I would like to keep him. Thanks guys

Regal tang usually are not reef safe once they reach a certain size mine loves zoa, soft corals and some LPS. Its been 5 years I think since my last one. Maybe the purple is following what the blue tang is doing .

How big is your regal? He often do you feed nori?

Most reef-building corals contain photosynthetic algae, called zooxanthellae, that live in their tissues. If your tank is of insufficient size, and the tangs are hungry . . .
