does that sound right? an 18x18x18=42g? thats what that AquaVol calculator thing said, but its for rectangular tanks. does it matter if its for rectangular tanks? im about to buy that tank for $30 so i need to know pretty fast
and would that be alright for a pretty small rhom for awhile till i move and get more room for a bigger tank? i already have 2 tanks (55 and 10) and im about to get 2 more (18x18x18 hex tank, and a 15 gallon tank for feeders) and everyones getting pissed off.
