Forgot to add, as soon as they get front legs add something floating to your aquarium so they can climb out when they want. Make sure the edges are not too high so they can reach the top of the floating object. I put a plastic lid in my aquarium, it has a low profile and works out great.
I have had toadlets with front legs for about 3 days now, and none voluntarily went to the floating "pad". So I grabbed one with the net and put him up there. He stayed about 5 minutes and jumped back in the water.
I also noticed these "tailed toadlets" will often swim for the surface, then float down to the bottom, often resting on their backs. They appear to be dead but they aren't. I don't think they are drowning as they were still alive the next day, though they don't eat at this point.
They are gradually turning from black, to getting gray colored spots on their backs. Also, their bellies are turning cream colored, just like a toad.
I suppose when their tail is mostly gone, their lungs will develop shortly thereafter and they will require more air. I'll watch them closely.
