hi. so i was away for two days and my little brother was feeding my fish for me. i came home today and my oscars were both kinda swimming with their bellies on the sand. they're swimming around now, but for a little bit they were just sort of swimming around at the bottom. my brother said they weren't doing that this morning when he fed them. they usually swim right up to the surface when i come in, hoping for me to feed them. they didn't do that this time, and when i did feed them it took them a minute to realize it. but they seem to be swimming around just fine now. also, one of my puffers [in the same tank] has some "fuzz" on his left eye. i'm setting up a hospital tank for him right now. a couple of days ago i added some sand [plain white freshwater aquarium sand], and a couple plants [java fern, some grass looking stuff]. i washed the sand and the plants before i put them in there. can someone tell me what might be wrong, and what i should do to fix it? my water parameters are all good, with nitrates and nitrites both close to zero, ammonia at zero. i just did a water change two days ago. any help is appreciated.
thanks for looking,
jessica
