Looking for small rimless tank
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.
