For various reasons I chose to temporarily move a 1.5" royal pleco, 1.5" sailfin pleco, and a 6.75" common pleco (named Aurora) into a 29 gallon tank together for about a week. There's also about 10-20 small female guppies in there. Didn't have a cover on it since it's temporary and plecos aren't known to jump. Threw an algae wafer in before bed. Woke up an hour or two later and couldn't sleep. Thought I'd watch the fish until I got tired again. Couldn't find Aurora anywhere. Finally found her 6 feet away from the tank. She had carpet fibers stuck throughout her scales. I immediately put her back in the water, fearing the worst. She was stunned at first but after ten or so minutes she returned to fairly normal behaviour. I moved her to another tank by herself for the rest of the night. I figure putting 3 pelcos in such a small tank was not such a good idea, but I'm not sure how her fins were damaged. Can other small plecos cause fin damage as pictured? Did jumping out of the tank cause the fin damage? Her fins were perfectly intact before I went to bed last night.
