I got a joke for ya's...
Go to Google,
type in: failure
and hit "I'm feeling lucky"
Back on topic. I'm not a big fan of bare bottom tanks, for an Aro they might be ok coz they spend all their time at the top, but I cant stand the thought of my fish living their lives in an empty square box
It would drive me mad not having any visual stimulation. Maybe the fish dont car but thats just me
