I'm using an Eheim Ecco 2234 with 200 watt Hydor inline heater and additional Eheim spraybars and intakes, arranged in a simple river setup. I also burried an airline tube underneath the sand in the back. The sand is actually larger than normal sand, so it doesn't get blown around by the current. I was told it was similar to pool filter sand.
It's still in the setup phase, but I got majority of the stuff moved in. I still have to move a big piece of wood and the bamboo shrimp hiding in the wood from my other 20 gallon high (24"x12"x20") shrimp tank. They hide well inside the wood, that it's hard to net them out of it. I just plan to move the whole piece of wood and hopefully the shrimp will stay on it.
The caves you see are actually about half the size of normal caves. They just are the perfect size for the juvies I have now. I'll be making more caves for new coming zebras. Eventually, I'll be making full sized caves when the zebra plecos become adults in the future.
The shrimps appear to be fine. The current doesn't seem to bother them. The zebras are actually more active in this setup. Either that or they're just curious on the new creatures (shrimps) crawling around the place.
