bulldog plecos

what are people's experiences with these guys? i understand they prefer a stronger current and slightly cooler temps compared to other similar cats...i have one in such a setup, and he's doing really well. i'm curious about their sociability. are these territorial like common plecos at all, or do they prefer being kept in groups? if so, how large a group?

the one i have is doing quite well, i am thinking i will probably just keep him as is, because he seems happy. no point in messing with something that's working unless there's an overpowering outpouring of dissent!

anyways, this seems right, i did some net research, and it seems several sites agree that they may quarrel with conspecifics. he's only in a 20L, so there's no way there's enough territory for multiples if they have similar temperments to the common plecs...

as always, i was just curious!

yea, mine consumes algae off rocks in the tank like it's the greatest treat on earth.
