My pond reaches temperatures as low as 20 F, rarely that low though. It does ice over from time to time in the winter.

Is there any variety of corydoras catfish that can live there? I found some pond shops sell catfish for use in ponds, such as blue catfish, but these reach massive sizes, I don't want something that will threaten baby fish.

    Why ? Koi are good scavengers and are vegetarians , and tolerate freezing temperatures. Danios ( and formerly swordtails , mollies,etc ) breed in my pond and are not bothered by large koi. Commented Jan 22, 2021 at 21:08

    Because they look nice.

    You can't see them in a pond unless it is a small bare plastic tub. Commented Jan 23, 2021 at 21:04

Catfish will grow big but also can't take that low temp that I know. Regarding Corys, same thing there is not one that can hold that low temp.
