I've been Setting up a river current tank for hillstream loaches and compatible tank-mates. The loaches will be the primary reason for the tank so whatever's best for them goes. Before I get them I have some time as I am ensuring the conditions are perfect for a stress free transition. The setup I'm brainstorming for current will involve a custom in-tank filter on one side where a pump will be situated leading to the opposite side along with any powerhead setup needed to stabilize the flow. Right now the tank is establishing and I moved a few algae covered rocks from another tank to give them a ready food supply once it spreads.
some things I would like to know about are;
-substrate experiences/recommendations
-experience with other set-ups for current (such as a powerhead manifold)
-tank mates that are compatible and are found in the same area that the loaches are in the wild.
-Plants and decor layout
Thanks
