I just have to say it....I love my pleco but he is a mess! When I got him he was about 3-4 inches and now he is 8 inches and poops all over the place! I did a water test and the nitrates were a little high, don't remember the exact reading. Lost a cory, a neon disappeared and another has pop eye. I was going to trade him to the LFS and get a couple of ottos but I really like him! I'll have to siphon some of that poop out couple of times between cleanings.
