I have a 55 gallon, that has cycled. I have 1 sailfin molly, 1 balloon-belly lyre-tail molly, 2 fancy guppies, 3 danios,and 2 platies (2 others have died).
About a week ago I noticed my sailfin had popeye really bad (almost overnight). The next day, the other molly had popeye on one eye. I treated with Jungle Fungus Clear, seemed to take care of the problem. In the mean time, female molly seemed to be pregnant, as she keeps getting bigger (now I know, it's dropsy!) Then noticed had Ich starting, so treated with Ick Away, for 2 days, seemed ok. Did 25% water change (well water, not city). Treating with Fungus clear again as all but 3 of the fish have something wrong.
Sailfin - stays at top near heater, one eye cloudy, tail fin looks like it may be fraying ( not sure if fin rot or ammonia burn)
Balloon belly - dropsy, popeye might be returning, one fin looks like it is bleeding (small amount) where it joins belly. Spends most of her time near the heater.
Guppies - Male -clamped tail fin, was hiding, but is now out. Female-looks great
Both platies - have fins that look like the sailfin, one has a cloudy eye, stay at the top near the oxygen bubbles from airstone
Danios - two are great, one has the same fins as the sailfin ( he was staying near the top and the heater, but now is swimming near the bottom, acting more normal)
The two platies that died, one looked great up till she died ( old age?) The other had the fins like the sailfin, then started swimming in backward circles, and died 2 hours later.
The tank is clean, not even any algae! 0 nitrites, 40 nitrates, ammonia close to 1 ppm. Did add ACE to remove ammonia today, now down to about .5 ppm. I know it sounds like I don't take care of my fish, but I really do. I'm at a loss. The last fish I added were the guppies 3 weeks ago. I do the water changes, everything was mostly fine till 3 or 4 days ago.
Sorry this is so long, but as you can see, I have an awful lot going on. If you have any ideas, PLEASE let me know.
Also, most of the feces is white and stringy. Thank you in advance.
