Can't wait to see him, EMG! Good luck with him! I just have to admit that Iceman is my favorite. His tail fin is still looking kinda stringy. Wish I could get it cleared up. I changed his water yesterday. How frequently do you recommend changing water in a case like this? It doesn't look nasty, like some cases of fin rot I've seen on these guys in the store. His tail is just a little stringy at the end, in spots.
