Who wants to play a round of "identify this creature"

Just in general (as in, they will spread through the tank) or specifically when trying to get rid of them?

I was going to try calcium hydroxide, but couldn't find it in the grocery store (legs isn't open yet today). Does lemon juice really work? Also, won't that affect the rest of the tank?

Yes, it works. The caution is that you don't do too much of it at once in a smaller tank. As you're adding an acid to your tank. You can also try white vinegar, or kalk paste. You know you've hit the thing (if you're using a syringe) if the stalk starts to swell and turn purple!

The little amount of lemon juice it'll take won't effect your tank. Why not go to your LFS and use kalkwasser instead?

Yeah, I think I'm going to go to the store and get the kalk. Then it's here. Right now, they only seem to be in a couple small pieces of new live rock. So I'm going to quarantine while I treat them. Hopefully there hasn't been too much spread in the mean time.

Thanks for the advice!

If they are only on a few small pieces of live rock; it may be worth while to take the rock out and either boil it or toss it out. Less of 'work' and effort required.
