:well don't fill the water all the way up, leave about an inch from the lid, so they can go up for air.
Gotcha! I'll pick up a screen top today as well. I have a glass top for the 2 gal. tank, from when I had a Betta in there, but I guess the froggies need more air than that.
:BTW what are u planning to feed them?
I have a variety of stuff that I give my fish, like frozen blood worms and brine shrimp and sinking shrimp pellets. (I won't use the fish flakes.) Is there another "frog specific" food to use? Do you feed them everyday? Will they nibble on plants too? I was going to put a few in the tank with them. (Probably elodia and java fern.) Thanks!
