Okay, well, maybe fish just hate me in general...My Harlequins have what appeared to be Columnaris (white tufts on lips) but when I put in some treatment it didn't help (I even did two back to back full treatments). Then, I get some gouramis, and I notice one of them has a litttttle white spot on his little arm fin. So, thinking I'll get ahead of it, I put in some Ich Guard. Well, that didn't help and now two of them have spots on their fins. Can anyone please give me some advice? The treatments aren't working for any of the fish and I am getting really discouraged . I don't want this spreading to the scissortails, and the poor betta and frog want to go back in their home tank. Any thoughts, please???
