Ficus repens in shrimp tank?
It works in an aquarium too. Or at least the stuff I bought does. The person at the les was unsure of what it was and searched around until someone knew. It was growing in and out of the tank. Looks really cool! I just put it in my tank and my oebt instantly started eating it. I tried to research it and couldn't find anything so I removed it in case it was toxic to the shrimp. They literally swarmed to it.
