It's a small 5-gallon tank with around 40-50 tadpoles. I've got a corner filter something like this without the bit at the top, basically just a straight tube into which I have an air pump line with a bubble stone to draw gentle current through the filter (which is just filled with stones) and aerate the water. The water is very yellow and foggy, I haven't done water changes--I really should, but I am afraid to hurt the tadpoles. I'm just using some standard tadpole bites for food.
When I saw the first with front legs last night, I put a plastic aquarium plant (looks like cabomba) that floats on the top. This morning we spotted another with front legs, so it's coming quick. My daughter wants to keep one and, honestly, I have no fucking clue how to take care of a frog--or a toad, this could be a toad. I'd probably build up rocks on one end and leave water at the other and feed it crickets, but I don't know if that's right.
Cool! What kind of set up are you running?
