These guys are IMO some of the coolest plecos to keep. They are very active, and when you keep them in groups even as small as 2 you will see a lot of interaction, not fighting. I had two recently, but one got eaten by a marble cat... sucky loss, but before the one got chomped they were absolutely awesome fish to keep. Mine were $40 a piece, but didn't have shipping costs, and were approx. 4.5". They don't grow fast at all, and are really quick to take the food. When I through algae wafers, lettuce, cucumber, carrots, or just about any other veggie they are right there eating in seconds. Just an all around beautiful pleco to keep.
