My good friend 5green was coming over to see my fish so we took a look at Finn and Dorothy and she pointed out that it looked like Dorothy had fin rot

. I have alwase put aquarm salt in but at the time dorothy was in a very small tank. I had ben planing to get him a new tank so I went out and got him a nice 2g tank with a bubble and underground filter

. He has made no improvement but has not gotten any worse. Witch is good

but then I took a closer look and noticed that there where tiny little holes in his fin

. This made me wory

. (He also has had a miner case of fin curling, if it helps find out wats rong). I was wondering if any of you know what this is or how to treat it.
Pleas no rude coments.
