I already know size matters
) but what i want to know does shape matter? I am about to buy an aquarium and was planning on a 30 gallon hex shape to put in a corner.
After some reading and discussing with fish people I am being told that a hex shape may be interesting to look at but not so good for fish...something to do with surface level and not enough oxygen at the bottom.
Looking a your basic community tank.
