According to @Jay Hemdal post about it, there is like some biopsy lab thing you can send the fish out to to try and figure out what it is. It’s $600 which tbh I have almost spent more than that on these wrasse already. I’m sure maybe others could chip in too, but I’m really curious about sending it out to a lab to figure out what’s going on. Not just for myself, but for others tooYea, I really wish someone would get down to the bottom of this curse. Some say it’s viral, and some claim other things. It’s a real mystery.
