i don't think your pb's gonna last long in that environment. On top of that, they are finicky to start getting to eat when newly introduced in a new tank. If its eating, then at least thats part of the battle.
I lost my first pb because I couldn't trigger it to feed... it died in about 2 weeks.
I tried again and when I saw it, it was very healthy and already eating at the store. I brought it home and noticed some parasitic bumps on the skin but I thought that keeping it fed with algae and healthy it would lose the parasites. I had it for about 4 months and it was very healthy eating seaweed like a PIG but I also noticed more parasitic bumps they were also getting bigger. So my foolish attempt to help it, I caught it in a fish trap and quarantined it. I treated it with 1/4 recommended dosage of copper to start and within 24 hours, it died
I really beat myself over the head with this one and it actually brought tears to my eyes when I found it. I later read that these tangs are extremely sensitive to copper which I beat myself over the head even harder.
I now have a sohal.... gave up on pb.
