I've heard of the hairy mushroom eating fish. That's in the Rhodactis family. So is the bullseye, but I've not read about them eating fish or small inverts. It's big, so keep available tank space in mind. They're also rather fuzzy looking and uglier IMO
. I had hairy mushrooms that I started to peel away since they just went crazy and weren't that nice looking in large numbers.
The mushrooms in the Actinodiscus family are those more common mushrooms you'll see. Bluish, reddish, striped, spotted, etc. I'd focus on those since they are much prettier anyway.
The ricordea won't eat critters either.
