If you can keep it off/out of the filter, it would be okay. My only objection to the idea is how difficult it will be to maintain water quality. I am contemplating setting up a tank with a UGF covered by an inch of gravel, then some peat, then more gravel and/or sand. Keeping the layers layereed may turn out to be a trick. I've been thinking about tank depth. Collectors report that Apistos spawn in 4-6" of water in the wild. Our 10-20 gallon tanks are anywhere from 10-12 inches above the substrate. Any one here ever experiment to see if raising the substrate/lowering the water level will improve the willingness of Apistos to spawn or brood care? My next tank set-up may be influenced by your results.
