5. Used to have them all over the place, One day I noticed I had hardly any in my 75g, but still had them in other tanks. After researching it a little, found that Centropyge angels can sometimes pick at them. I have a potter's angel. That said, I've never noticed her picking at hydroids specifically, but I thought it interesting to note that all of a sudden I didn't have as many in the tank she's in. Could be coincidence, but still noteworthy.

Good luck. In the grand scheme of things there are worse things to get but they're still quite annoying to look at especially when they spread all over the place.

You've stumped me, what is worse than hydroids? I've had flat worms, red bugs, aptasia, bubble algae, hair algae, cyano, big ugly crabs, ick, and probably a few other things plus invasive softies like anthelia and GSP but I cant think of anything worse than hydroids. Blow torch them is my advice.

Oh I agree, they're up there but I still think they are not the "worst" thing that can happen to a tank. They won't cause you a tank full of dead fish inside of an hour just because you annoyed them, for example. (Hmmmm, maybe I should add "as far as I know, anyhow" ... just in case!!)
