that's a cool tank! I have the exact same tank with a smithii in there. Do you find the Ac filter too much flow? For my heater I have one of those little 7w hydor heaters. Only problem I have with it is you can't turn it on or off.

Very cool..

I would ditch the heater in there. You can get heating pads for a small tank that are 7.5 watts. You can buy them at Pisces for $20. Chiragra are extremely hard hitters.

What color is that Chiragras Meral spots though? Can you get a pic?
