I actually have a pair of old 220 gallon Whisper "hot" filters on this tank, so there is a pretty fair water movement
this is some of the info I've gleaned of the www... ( you know there is nothing but truth of the www )
"Most of the initial research into this species says that they are a cool water fish that must be kept in a river manifold tank with fast current and high oxygenation. We have personally kept them in hot water tanks with clown loaches, unheated setups with goldfish, and even heavily planted 20-gallon tanks with gentle sponge filters – and the hillstream loaches happily thrived and bred in each of those different settings. In our opinion, what they really appreciate is a stable pH (preferably from 7.0-7.8) and good water quality. Any kind of fish tank filter will work, as long as it’s appropriately sized for your aquarium and the other inhabitants can handle the flow"
