Potential hydroids taking over

[Webbler]

What was supposed to be a ‘clean’ tank building pod population has exploded with what appears to be a couple different types of hydroids. Can someone confirm? Any potential predators to knock them back? Options?

The rock is picking up steam with what appears to be the same minus the webbing/branching.

Yes- you have digitate and colonial hydroids
They are happy because they’re getting food. Aim water flow towards them, not at them and they will not be able to capture food and will starve
