Free swimming hydroid removal?

[Nooonan]

I have a 60 gallon seahorse/macro tank that's about 3 months old. Today I was doing a water change and was siphoning in the caulerpa bed to remove left over mysis shrimp. Once I was done removing the water I glanced down at the tank and in one corner I saw a ton of activity, almost as if the water was boiling but it was just the movement of a few hundred tiny jellyfish looking hydroids. I used Julian Sprung's "Thing" to remove a good amount of them but there is still a lot in the tank and attached to the glass.

I am not too concerned right now as my H. reidi seem to be unbothered by them and these typically aren't an issue for larger species of seahorses but I've never had to actually deal with them and I am just wondering what my best plan of attack for removing them might be. I've read that peppermint shrimp as well as some nudibranch may eat them.. I can definitely introduce a peppermint shrimp sometime if needed but I wasn't sure if there was anything else that I should be doing.

Thanks in advance.

If their anything like colonial hydroids, a peppermint shrimp won't eat them. A Lynx Nudibranch is supposed to eat them, if you can find one.

They will fade in time, you don't have to do anything. I rather enjoy them. I used to have them in my seahorse tank and it won't bother them. The only place they are a "pain" is in the seahorse fry breeding tanks. Where your tank is new, it has extra diatoms and film algae. That's promoting the growth of pods. Those pods are being eaten by the hydroids. It will balance itself out.
