I've been reading up on these guys, I would like to have one in the 120g planted tank I'm planning.
A lot of people seam conflicted on this issue. Some say they eat plants, others don't. It would appear that through everything I've read, they CAN eat plants, but generally won't if you provide them with better alternatives (like fresh vegetables).
I know these guys get large (1-2 feet) which could be the other problem ... when they swim through the plants can they destroy them/uproot?
Anyone have one of these guys (an adult pleco) with plants? Does he cause you problems making it more work than its worth to maintain?
