I bought a that same pleco a couple of weeks ago i put it in a 29 gal with 2 clown pleco's and the clown's killed the leopard pleco. They where all just over 2" i was surprised the clown's did that because they seem shy and hide alot the leopard seemed like it was out and about and just a more robust pleco than the clown's but maybe the clown's tag teamed him. I saw what i thought to be injury's from aggresion on the body and he looked faded so i guess the clown's sucked off the slime coat i wish my leopard was meaner he would still be alive.
