iv found 2 threads for you from another place i vist, i dont no much about them but i will paste there threads.
Yes they pack a powerful sting, I wouldn't touch with your bare hand. They are very hard to get rid of. You can find several post on here if you do a search. To rid them is a battle and depending on how many you have the methods can very, but get rid of them as asap before they spread to the whole tank. I fought mine for at least two years. You can try covering them with a kalk paste if it is only a small area. If all possible remove the rock they are on from the tank and battle them outside of the tank. This will help in keeping them from spreading. You could also try removing the rock and use a hard bristle brush to scrub them off the rock. I have heard some poeple use tweezers to remove them from the rock, but that has to be some work. You have to be sure to remove all trace of them including the runners or they will grow back. I finally had to remove the rock from the tank and placed it in RO water in a covered trash can for about a month. After that I scrubbed the rock and blasted it with a hose rinsed it and placed it in a covered trash can with salt water for another month. Unfortunately this kills the whole rock, but it was they only way I could win the war. Good luck. |

and this one
First off, hydroids are not a worm, but are related to jellyfish. They are only on the outside of the rock and are attached to it by stolans which will look like roots that spread out across the rock or whatever they are attached to. Mine would sting the daylights out of my hands and would leave welts that would make my hand swell. They didn't seem to have any affect on my soft corals except to compete for space. However, they overtook and killed my sps corals and xenia. If you only have around 20 or so, I would try using kalk. Just mix some kalk with tank water until it is a thick paste. You can then put it in a syringe or maybe a turkey baster and then cover the hydroids completely. You might have to apply it a couple of times. If you are doing it in the tank turn off any power heads in the tank so it won't blow the kalk around while you are applying it. Just make sure the kalk doesn't get on any corals in the tank. |

I have never heard of these digitate hydroids to be frank so I cannot really comment on the extent of the problem but in general terms if you don't often hear about something it it ain't generally that bad I wonder if these beasties get a bad press in a similar way to bristle worms?
I have numerous beasties that fire threadsa all over my rock after lights out and they have never caused any problems whether these are one in the same as yours I don't know but I don't tend to worry about unknowns to much as they are pretty much that unknown until problems occur you could always post a question to practical fishkeeping to see what comes up there. |

you could always move over to keeping malawi and tanganyikan cichlids instead.
much cheaper, easier and great fun to keep, plus having babies makes it realy interesting. |

From what I have read in the last 10-15 minutes they are not a major problem unless there are high organics in the tank they usually die off after a month or 2 pressumably they starve to death. I would say if they are not harming anything they are not a problem incidentally the addition of live rock would introduce far more competition for food and would also add to their demise I suspect. |
