Guppy Problem - Need Help Fast -

[wr3ckin_cr3w06]

Hi, I have a 10 gallon aquarium with about 10 guppies, a pleco, some ghost shrimp, and 3 apple snails. I recently did a full water change after I noticed that someone else began feeding the guppies and the left over food was beginning to mold. Since then, about 4 guppies have died and 2 more are now showing symptoms of the deceased ones. They're just swimming at the top with their mouth near the surface. They are not gasping for air, just swimming around the surface. They eventually get weaker and just drift along the surface until they hit a plant and just float there until their dead.

They do have white fuzzies on their side fins. I've treated for Ick at first, then added aquarium salt and just last night tried melafix. Now one of the prettiest males just started floating. I just uploaded a video of the male in trouble on google.com that I can post the link to, if anyone thinks that will help. Sorry for the long message, but I don't know what else to do!!

I've had the same thing happen to my guppies - they just start swimming slowly along the surface and then die. Really unsure what causes it, but it sure sucks. It was suggested to me that their diet might be to blame, what do you feed them?

Your tanks overstocked.
Water change and increase aeration in the tank.
Can you post water stats in ammonia, nitrite, nitrate, and ph.
