I found my yellow tang stuck on my wavemaer cage. He was doing fine the day before eating. He had pop eye but it went away that day after. So I believe he died from getting bullied or maybe flukes made him weak. Than I started looking at the fish closer and on my foxface I can see clear white thing on the top of his fins which I believe are flukes. Idk how they got there because I qt all my fish in prazi pro for the recommend time. My system is 125g and I don't really want to kill off all my worms in my tank but I can't catch the fish without destroying the tank. So my only option is to treat the tank. I was also wondering if a sea cucumber is safe in prazi pro l.
