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

sounds right, but for piranhas it is all about the foot print and 18" by 18" is not very big

10 Hexagon 14x12x18
20 Hexagon 18x16x20
35 Hexagon 23x20x24
60 Hexagon 27x24x28

im guessing its only 20- 25 gallons

does anyone know a calculator for hexagon tanks?

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.

I can make up a formula for it.

5 X (0.5 X edge of one side X half of width of aquarium) X height

then divide it all by 231 to get gallons. This only works if it is a regular hexagon, meaning equal sides and angles. Otherwise I dont think there is a set formula.
