Toad tadpoles turn quicker to toadlets than frogs do to froglets. So that is
good news. Also depends on temperature and food available.
Can they get out now that they've gotten in? You don't want a bunch of drowning
toadlets, what a mess!
If they are toad tadpoles the fish are leaving them alone because they taste
bad. They'll try one and spit it out.
Look at one closely. A toad taddie has a whip like black tail. A frog tadpole
has a fine membrane of skin around its tail, almost translucent in some.

You can try netting them out into a kiddy pool filled with pond water and pond
slime. Or give them organic lettuce to feed on. They may or may not make it,
jammer's did not make the transition, so if yours do let me know.

Toads are a popular food of hognose snakes and skunks.

good luck!
