oh yeah, def prime bichir real estate. Also I've heard plecos are bad for polys cause they take their slime off, I haven't seen this for myself. ANy other reasons?
Whoa! I actually gave someone an idea! The cave looks great man. Hope you and your fish enjoy it. Another trick you can do is build a cave using one of the sides of the tank. That way your fish think they're hiding, but you still get to see them.
