I had toad hatches very similar, but I don't have any predator fish in the pond yet.
A few 5" YP that went after the toad tadpoles when first stocked, but spit them right out. They must not taste very well.
I've still got clouds of them along the banks. Although they are getting bigger.

12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
Otter attack in 2023.
