so I'm happy to announced that my lyretail Mollie that was supposed to be dying of swim bladder desease is not doing worse at all!!!! By now all my others where usually dead (5). So, I increased the tem a little and started treating with melafix without the filter and what do you know. I don't want to jinx myself and say that he is all better but he looks good!! I'm feeding as little as possible and have not made any water changes for 4 days to let the melafix work. And on another note, I'm getting my 30 gallon tank this week, found it cheap on eBay. Now I have to figure out if I want a fushless cycle or TSS start with my current fish. Anyone has a predilection?
