Just wanted to add a comment, I have no experience. I have read that a bullfrog will eat anything that will fit in his / her mouth. It could be risky to have your baby turtle outside.

I did consider bullfrogs . But in seven years of obsevering my yard and eight months with a swampy gold fish pond i have never seen or herd bull frogs . The tree frog i mentioned was bitten bye the turle the night i posted lol and has not returned.

Prior to lebrons intoductiom to tje pond i had always wished for bullfrogs niw i am happy it never happened

Just leave them both alone <3 That turtle is not going to eat that tree frog and that tree frog won't let it happen..... I say let nature be.. they have all co existed long without humans thinking they need their help in the first place.... We have a big pond with bass, bluegill and crawdads....We have this pond to enjoy what nature gives and takes <3
