I'm looking for a small rimless tank, preferably less than 6 gallons, and it has to be long. For lighting I'll be using a Fluval 13w CFL clip on. I'll be dosing for CO2 with liquid CO2, the kind they sell at Petsmart in bottles. I want to grow microsword, guppy grass, dwarf baby tears, dwarf hairgrass, etc.

Inhabitants will probably be 3 female bettas (if the tank size is 6 gallons, if it is smaller, probably not.) or some cool crawfish/crayfish/lobsters/crabs.

Most crays, with the exception of Dwarf CPO, will devour all the plants you list.

JBJ Picotope is 3 gallons.

Mr. Aqua has a few smaller rimless tanks. So does ADA.

Take a look at the fluval spec: http://www.plantedtank.net/forums/showthread.php?t=197065

I love mine and it'd fit you perfect

(I also have the same light you're going to use on mine)
