go with cardinal tetras for tankmates as they like the same water params keep temp between 80 and 82 ph at least for spawning purposes needs to be in the low 6s a great setup would be a 20 gal or so with co2 (for plants with the added benefit of lowering ph and softening the water) with power compact lighting you can pick up these up fairly cheap and co2 setups arent that expensive either unless you buy a ready to run kit check classified adds on this and other sites as well as e-bay and you can make a fairly cheap setup only prob with co2 it works better with a canister filter rather than hob filters due to surface disruption depletes the co2
