Nudibranchs

[mikemdvm]

Is there a good reference to help tell the difference between good nudibranchs and bad ones? I try to get good pictures but they are so small it's hard. I have a fishless tank (velvet) and now I'm seeing more nudibrachs

Also any inverts that will eat them?

Try to get a picture, it's the only way to ID what you have.

Most bad ones are obligate coral eaters meaning they eat one type of coral. I would just google whatever type of coral you have with nudibranch. Such as montipora eating nudibranch
