Hello all. I'm hoping someone can help me with some fast help. Today when I came home from work and fed my fish, I noticed my bristlenose pleco under our fake driftwood kind of just laying on his back and his belly is all bloated. :'( I touched his tail and he swam away a little bit and hung upside down for a minute before dropping back down onto his side/back. I've been reading through some other posts and I'm about to try and give him some peas with the hopes that it is something simple. I haven't noticed any of his poop and haven't fed him anything but the algae that's in there and whatever flake food is leftover. I'll try to make this as short as possible: Our power was out for about 3 hours yesterday - the temperature never got above 80, normally keep it 76 - 78. Tank has been up since 2/22/10 - ammonia and nitrites test at 0, nitrates 20, PH 7.8. I did a 20% water change yesterday to help oxygenate the water and also because my nitrates have been a bit high. Will do another water change tonight to try and lower them a little more too, but have been doing changes weekly. The tank is a 20 gallon and has 3 tiger barbs and 2 green tiger barbs besides my pleco. I have a piece of real driftwood in there for him too. We had quite a bit of algae since the tank sat for a month while it was cycling and I didn't clean it because I knew I wanted my pleco. I tried to take some pictures of him, one is obviously clearer than the other, but one is also closer up. Please help!
