I have a 10 gallon viv with 2 D. Auretus living happily. Decorations include a couple plastic plants, a coco hut, and a water dish. I'm hoping to switch over to a false bottom with a water feature and live plants. So far I've bought all the materials including some pothos plants, a creeping ficus, and a coco husk sheet for the back wall. I've read that stagnant water in a false bottom could cause problems, so I'm looking into adding a waterfall or stream to circulate the water. I already have a freshwater aquarium with tetras and swordtails that makes use of a sump to maintain water level and make water changes easier. With all that said...what are the concerns of tying my viv into the aquarium sump. Are there any problems with the frogs and fish sharing the water (i.e. toxins, waste, etc.)? The sump has mechanical, chemical, and biological filtration and a heater (set to 76 degrees F). Any comments and/or concerns would be greatly appreciated.
