Well I got it. Love it! Mines pretty big and my little guys are really happy, the dumpy tree frog is healthier than he's ever been. The shape seems more conducive to the wandering of frogs than a fish tank.

Square vs rectangle, the toads want to wander and have their territory on the floor of the tank,while dumpy stays up in the tree I built for him ( except when he bathes). Seems to be more circular where fish go back and forth keeping territory in varying heights as well as locations more of an elongated venture. Oh well, just my hobbyist observation, not an expert.

dicy~ How would you do it and keep the temp up without a screen top? I can't use a heat pad cause I have water in the bottom of the tank and it would boil my fire bellied toads so I have always used lights from above. Without a light/heat source everyone would be pissed and die out of spite if not by freezing. My curiosity is peaked!
