My male sunset platy is moping around but I can't determine if he is ill or just moody. He seems to be staying in one place more than usual with all his fins (particularly his top fin) slicked back. He doesn't appear to have any external spots or anything on him and he is eating just fine. He also gave a pretty good chase when I tried to take him from the tank to the hospital tank for observation. While he was swimming around his fins looked just fine, but afterwards (about an hour later) it was like he went to sleep and they drooped again or something. I noticed that when he was hanging out near the bottom a couple of my guppies seemed to be pushing him by jabbing their noses into his side. When they do this he seems to lean over to the side a bit for a few seconds and then rights himself. My water levels are fine, although I keep the tank at a relatively high PH/temp (8.6/79 degrees). The nitrates are a little high because I have lots of live plants, but still in the safe zone and are pretty stable. Everyone else in the tank seems to be just fine, including my 2 other platties. Should I be concerned?
Thanks!
Thanks!
