Faster growing with high water flow

[Potts050]

Some of the garras, a few loaches, torrent cats, some madtoms, and some hillstream loachs, stonerollers, stone carp, and some Barilius species all do best with current. I don't think that they grow faster but they stay healthier and live longer than if they are kept in still or slow water. I have been told that payara are the same way.

Ensuring oxygen saturation is more important than high flow rates i would think, in ensuring health in these fishes.
