Kole tang still not eating!

[Reef Pilot]

I would like to suggest hypo in a QT. But unless you have one already set up fully cycled and mature, chances are not good for that to work either. Hastily set up QT's usually don't work. And as you said, catching him and moving him again will be stressful.

Ich usually subsides a bit every few days. If you can get him eating during that time, and maybe some immunity might kick in, you (he) might get lucky and survive. But I honestly don't like your chances.

I don't know what else to suggest at this stage. Good luck.
