Yes, I am aware of how big it can grow (even when I was given the wrong information from the LFS about what type of pleco this one is). It is possible that its growth may become stunted based on its environment. I have 4 other plecos (Golden Nugget, Green Phantom, Gold Tiger, and Blue Panaque), so I will probably have to come to some kind of decision down the line as to whether any of them will need to be re-homed. I have a 72 Gallon Bow Front tank (4 foot wide).
