I have a male and lemon blue-eye in a community 40B; i wish they wouldn't breed; but i have a gazillion and 1 little pleco of various sizes. The nannacara hunts them but they pop out faster than he can get em - when i move in a couple of months i'll round them all up and give them to the LFS - so yea two pleco == gazillion pleco (pot optional). I will say that before i gave him a cave he went around the tank digging holes. I had to give him a cave so he would stop digging; and yea - for the past 3 years it has been his cave and everyone else knows it. The nannacara is at heart an ambush predator - he will sit just above the cave for days waiting for snacks to leave.
