Currently I have 1 Hillstream loach hanging out in my tropical tank, and I know how bad that is for him so I'd like to upgrade his living arrangements.
My plan would be to get a 30g long at least (bigger if my criagslist haunts are particularly fruitful) and get a nice river setup going. Other inhabitants would be more Hillstreams, my danios and (hopefully) Weather loaches. I live in a basement so it's perfect for keeping these coldwater fish comfy.
What sort of powerheads would I need for this setup? I was thinking of getting 2-3 of them all at one end for a more uniform current (intakes at the opposite end) but I'm not sure how many
GPH would be ideal or if there's a specific model that works best for this sort of thing.
