Lower the water level to just enough to cover the tad. Then tip the container slightly and provide a leaf or moss to enable the tad to climb out. I place my container into the temp habitat about 5- 10 gallons, no bigger, that's been seeded with springtails and already has a few melanogaster ff In it. Wingless are best as they don't jump as far and make easier prey. The smaller tank allows you to observe the froglets behavior and feeding habits. The tadpole still has to crawl out of the water and absorb its tail. While it absorbs its tail, the tad will not feed. You can concentrate food by placing a small slice of banana or strawberry in the tank. This provide the flies a place to congregate and lay eggs providing larvae which are more nutritious for tadpoles. While the tad is in the water feed lightly. Once you see the froglet actively hunting, feed one to two times per day but feed lightly and please dust all food items with a calcium supplement and vitamin supplement. Frogs require vitamins that "home grown"insects don't contain. You're doing great so far.

The way I set up my grow out is I put down a layer of moist sphagnum moss, then ABG substrate with springtails and isopods. I place a plant clipping in and cover the ABG layer with leaves. Lots of leaves. This allows the froglet the security and hunting grounds it requires and it gives springtails a place to crawl and ff a place to hide as well. Foraging is an important skill for the froglet to practice. Best of luck.
