I'd needed... hydroids?

[prsnlty]

@twilliard I was told this is a hydroid of some kind and to get rid of them they need to be crushed and covered with superglue. My tank is LOADED with them and that is a totally unrealistic option for removal. Do you have any information or fix other than to break the tank down and the option above? I have a coral heavy mixed 180g reef.

Vermetid snails.

The black ones don't move around and don't appear to have mucus coming from them. They are very hard and attached without long tubes although I can see the ones under the monti being vermetid's . If the others are also why do they not have long tubes?
