Hello all,
I have a few questions for all you experts to laugh at. First off, I have positively identified a hydroid colony growing on my live rock. Well, actually a few, but they are small. First off, I am curious as to where they came from. I have not added anything living for nearly 4 months. I use synthetic salt water, but I do feed frozen mysis, brine, krill, etc. Could eggs (sorry, I forget the proper stage name) have come in with the food? I also have noticed that I now am the proud father of a nice population of some type of mysid shrimp that have also appeared long since my last addition to the tank. From my understanding, even if these hydroids progress to a free-swimming stage, they will not survive because they will bump into the glass and die, right? I am not looking to raise them becuase obviously its next to impossible, but I don;t want any harm to come to my fish. One last question. I was lucky enough to get a Stomatella varia as a hitchhiker and have watched him grow for a few months now. Well, I had to move my tank yesterday (everyone is happy and doing well, thanks) and he ended up crawling around in the bucket that his rock was placed in. I went to ease him off the bottom when he curled up. I figured, great, that was easy. But as i placed him in his acclimation bag, he dropped a significant portion of his foot. I am assuming it is a similar defense mechanism to lizards dropping their tails. Has anyone else heard of this happening. He resumed his travels after being placed in the tank as happy as a well, stomatella. Thanks for the input guys and gals, but now I must be going.

The hydroids can spread. I'm not positive, but I think they do it asexually. Easiest way to get rid of them (or at least keep them in check) is to rip out the tubes from the rock they're on.

Stomatellas will do that with their foot. They survive just fine though.

HTH!
