how are poly's in a planted tank? mine's still small but but he's in a heavily planted tank with a spotted ctenopoma and they both seem to love the tank and each other.
are they cool with a sandy substrate or should i just stick to gravel. also mine seems to like to perch himself on top of a large flat rock in his tank, is that normal? he also wedges himself in the grooves in the side of the rock. i don't think he'll be able to fit in there much longer though. that's just like poly's, full of character!
