Okay, the eggs on the plants in the kiddy pool apparently are two different
things. Some of them look just like baby guppies, so I am guessing they are
some kind of fish. They swim like fish. They are greyish and well, they
look like guppies to me. I called the farm store and they said some fat
head minnows were in the tank with the plants I bought..

The others just keep getting longer and blacker with one end round and the
other end flat. The ones that are hatched flutter around a bit and hang
vertically from the plants to rest.

I netted out everything that moved and put them in a tub with a water lily.
I put the plants with eggs I could see in the tub too. Everything else
gets some of that PP stuff as soon as my husband gets home with it.. I got
rid of the snails with some lettuce leaves.

Will the little fish and tadpoles eventually eat mosquito larvae or should I
put a mosquito dunk in the tub?

I went outside with a flashlight last night and watched the frog that
moved into the pond the day after we filled it up. I've seen him a couple
of times early in the morning but he disappears as soon as he sees me,
He's big for a frog I think, and sounds different than the two over by the
kiddy pool. He's not so loud, mostly grayish green with huge eyes. I
think he lives in the mud underneath the pickeral weed. If so, he probably
has been there for a year, because we grew the pickeral weed in an old sink
last summer and I didn't repot it. I just picked it up and moved it into
the pond.

Anyway thanks for the advice on the PP stuff and all the other help.
