I believe the golden puffer I have has come down with ich. As of right now there is currently a red breasted wrasse and a zebra eel in the tank. On top of that the 90g I have is currently being used as a qt for the fish I was going to put in there in a couple days. How do I go about treating this? I'm not sure about the treatment with an eel in the tank. Any advice is much appreciated.
. Also I asked a mod to merge your two threads for you, that way all the info is in one spot.
