well, I got it set up, I am running a Fluval C4 HOB
filter, lighting is a 30" AquaticLife 2-bulb T5HO for 2.4 watts per gallon, my substrate is Flourite Red, I have added a small piece of driftwood, a bunch of river rock, and for the moment planting consists of Wisteria, Green Temple Hygro, Limnophila, Corkscrew Val, and a few smaller Cryptocoryne species, any recommendations for fish? will not be stocking it until the nitrogen cycle is established, just looking for ideas as it's been a while since I've done a tank this small.
Okay, here's a better question, would a small school (6) Tiger Barbs work in a 20 Long? Some sites say they are fine as small as 10 gallons, others say nothing less than 30, would they work in a 20 Long?
