I just bought an upside down catfish from my work (Petco). It was an impulse buy, I just thought that it was the coolest thing. Anywayz, there is Ick in the "system" but the tank that he was in didnt seem to show any signs of having Ick. I can put him in my 3G to treat him. But like I said he isnt showing any signs. Would he if hes scaleless? Should I treat him?
