Noticed this on an SPS frag I recently got, looks like a type of hydroid. Anything I should do?

It does look like hydroids, given that they've encrusted the plug at least as fast as the sps, I would break the sps off at the trunk, keep the top part, and throw away the bottom. The sooner the better in case they are ready to reproduce.

For future reference is there a dip they don’t survive in? This is the only one I have that’s got them.

Hydrogen peroxide might work.

I honestly don't know, they're fairly resilient and tough to treat for on a whole tank, but while there may be a dip that works, anything concentrated or strong enough would probably damage or stress the across more than just cutting it.

I would presume careful application of hydrogen peroxide to the base or a strong dip solution dipping only the base for a minute or two would work, but I don't know if the acro would recover faster/do better compared to just cutting it.
