I have a 55gal going. I have a puffer, trigger, snow flake eel. I just put a tang in about 5 or 6 days ago. He know appears to have ICH. none of the others have any signs about it. I would like to use hyposalinty but I am getting ready to go on vacation for 10 days. The person feeding while I am gone has no idea about taking care of fish. What do you suggest I do so I don't come home to dead fish.
