Do Goldfish (Sarasa Comets) or Butterfly Koi eat Frog tadpoles?
We have a pebble beach area that was made for growing bits of algae, a place for fish fry to grow, and a place for frogs/toads to breed. We recently got ~400 full grown tree frog tadpoles from my parents pool liner. They're just starting to sprout legs. I put them all in our pebble beach area and added some water.
Normally the younger fish go up there and pick out all the fresyh algae when the water level is raised, but this time it seemed like there was added fervor (or maybe it was my imagination) and am afriad the fish ate all the tadpoles.
Now I konw the fish absolutely refuse to eat American Toad tadpoles. They have a toxin in their skin, and when eggs are laid, they're never touched, and we have THOUSANDS of toadlets that leave en masse. but I've never seen that situation with frogs.
So, what have you all seen/experiences or learned about this? Thanks!
