They have all been happy and healthy for about 1 month and a half, since I got them. Until last week when one of my fish mysteriously died -- I found her at the bottom with an orange-ish stripe by her belly. And now I just noticed my painted platy (female) is not swimming straight and has trouble stabilixing herself. She is very active (more than usual) but she keeps bumping into things. Also, her scales are a little faded from the black they usually are. I have her isolated in a 5g right now but she doesn't look too well. She shudders a lot as well... Any idea what could be wrong? I clean the tanks every week and a half, ph, temp, and ammonia seem fine. They are all eating normally. I just can't figure this out... ajoy7 2010-09-05
