Hydroids, Now what?

[megs_clark]

I had hundreds on my glass a few months after starting my tank and they disappeared all On their own. They didnt seem to bug anything and only lasted a month or two!

From what I understand, those guys are a pretty normal occurrence at some point in a tank's life cycle. They flourish for a bit then seem to run out of something that they need and all vanish.

There are much nastier hydroids to avoid getting, like the browny orange ones that look like bottle brushes and form massive, unstoppable, coral killing carpets.

Just be glad they are not the hard tube hydroids
