i added a bristle nose (golden) pleco to my community tank 3.5-4 months ago. I never saw him again after the second day. This morning while drinking coffee and looking at my tanks, finnex 24/7 on dawn mode, I saw something that looked abnormal. Initially I thought it may be a pepper Cory but the tail wasn’t up, the fish was flat on the substrate. I got closer and saw the golden bn pleco, about 3” long. I had looked for his corpse months ago and never found it. I have 2 double sponge filters hanging on the back of the tank. I think he/she hangs out there during lights on.
