hey well i already asked if io should take out some gravel rocks in my 60 gallon because i feel theres just too much maybe its like a inch from the ground do you think thaTS TOO MUCH? i read that haveing too much rocks is a crap collector and well all i have in my 60 gallon is my arowana and well we all know i wont be able to put any other fish in there except my aro so it wont really need bottom rocks...i guess i just used it cause its nice and i need ot stuff my live plants down into the rocks...any suggestions?
