I voted "yes totally."
I guess with any angel there's always the "it varies by individual" thing, but I've now had two potter's angels (the first I lost in a tank move incident when I moved into my current house

Man I miss that fish, she was one of the nicest I'd ever seen.)
Anyhow, both were model reef tank citizens. I have clams, I've had SPS in there (they are not the reason I don't have SPS - I'm pretty sure

), LPS, softies ... never had a cause for concern.
To be fair I don't know 100% that my potter's is the reason I don't see hydroids. But it is true that I did used to have a lot of hydroids and for whatever reason, I don't see them anymore. Might be the potter's, might be the CBB. I haven't tried the experiment yet to see if either of them will pick at them.
