Hi. I'm In the U.K and am new to keeping a.d.f. I recently got two and put them with my Betta and 4 shrimp, but I have now got them their own small tank, as I was worried about them not getting enough food, its about 17 litres I think. It's set up with sand, a couple of plants etc and running.i filled it with RO water with minerals. How long before I can put the frogs in and could I get maybe a couple more when they are settled. Any advice re their care etc very welcome.
