I've got over 20 medium and large goldfish + at least 30 mosquito fish

fry and it can only be gold or mosquitofish.

Depending on the mosquito fish type, they are voracious on other species
fry and eggs. I had 1 mosquito fish in a kiddy pool and never saw any frog
spawn, even though there were plenty of frogs hanging around. Took out that
one fish, and all of a sudden I had frog eggs. While they were in the koi
ponds, never any koi fry either. Luckily they died off when I went to
constant slow flow in the winter. Apparently they couldn't take that slow,
but very cold water, flow at the surface. I don't miss them. ~ jan
