For those who think not much can be done with a hex tank

They'd make really cool giant ant farms. ;)

Seriously though, I'd probably make them into vivariums with boa constrictors or water monitors, myself.
 
Niko ? Guppies ? :omg:
 
jesus christ that would make one awsome effing tank! move over car im savin up for that! i would put...... omg i cant think of what to put in it there are so many ideas brewing in my head!
 
Those are octagon's not hexes :p

I'm actually aware of that, but i didn't realize I need to be specific in the comparison. Not much of a difference between hex and octagon shaped fish tank when talking about practicality of applications.
