Hi guys I need your help with one of my Plecos! So I wen’t out today for about 2 hours, before I left my albino Pleco was perfectly fine and working on cleaning off the fake plants in my 35 gallon. After I got back about 2 hours later I realized that he was at the top as Aphrodite (our female betta, was inspecting him and I noticed her) and him just floating there on his side against the glass. I thought something might be wrong and upon closer inspection there is. He appears to be in really bad shape, he looks like he may have been attacked as he has significant (what appears to be) bruising all over his body, blood in his fins, joints, and along the sides of his stomach. His stomach also appears to be slightly swollen and he seems to be bleeding from the anus. I will post multiple pictures so you can see in a moment but was wondering if anyone knows what’s wrong with him. I’m very worried about him as we got him about 2 months ago and he’s been doing great but now he’s floating on the top upside down and can’t seem to stay suctioned to the glass like he usually does. All the fish have coexisted wonderfully for the last 12+ months together so that’s why I’m at a loss as to what might have happened to him. I thought that the other Pleco might have picked a fight with him and he lost badly? I’m also worried that he might have somehow developed a bacteria infection but I’ve never heard of it happening in 2 hours as he was completely fine this whole week and displayed no other signs of illness or any other problems. Any advice on him; what might be wrong and how to fix it would be greatly appreciated. My tank setup: 35 gallon hex 2 fantail goldfish 1 dwarf Blackmore 4 loaches 2 tetras 2 barbs (they are actually very well behaved and usually refrain from any fin nipping) 1 female beta 2 bumble bee catfish 1 striped Raphael catfish 2 Plecos (1 albino the ones who injured and beat up) and one black one I know we have too many fish in the tank and will be getting a 150 gallon in a months’ time. Water conditions: Water clarity: excellent Feeding: Hikari Gold crushed pellets and Hikari Tropical Algae Wafers supplemented with frozen brine shrimp, blood worms, zucchini, baby spinach leaves, and the occasional other vegetable and fly. Fed once a day only as much as is eaten. 35% water change done every 3-5 days or sooner as needed. 80% water change done every 15 days. Filter cleaned regularly and scrubbed once every 3 months.

Doing a water change today 1x 23 watt CFL Magnum 80 gallon Canister filter Water tests from December 6, 2009: PH: 6.6>7.0 Usually 7.6 Ammonia: 0.25>.0.50 Nitrite: 1.0 Nitrate: 10>20 I'm new to the forum here and am not sure how to post pictures so I'll create a blog and add them to it as soon as possible for you guys to see.
