Thanks for the ID suggestion. I am keeping them with about that ratio of "land" to water with less than an inch of water as all have legs but some still are swimming mostly. I found this out, that the crickets looked like monsters next to them; I will be purchasing a fruit fly culture quickly.
At least four froglets are spending most of their time on the land section. Very exciting, I have had them for 11 days so far. When I first got them they were pea-sized tadpoles with no legs.
I really appreciate the information. I got pretty frustrated this morning messing with crickets. I will try ants until the fruit fly culture arrives. Hopefully I can get better pictures.
