I observed this critter in one of my store tanks for about two months. I have unfortunately moved and never managed to get better photography so I'm afraid this will have to do. I'm just fascinated by them because I have not been able to ID them for months! I have collected a couple other posts that contain pictures of something that looks similar— so far, positive ID has not been offered in any of those threads. They seem pretty rare compared to digitate and medusa hydroids. Whats unique about this animal is that each polyp has a holdfast, as opposed to other branching hydroids which have colonies that extend out into the water. Perhaps this body format is an early stage of those other hydroids? Flow too high to risk forming an appendage?
I'm starting to worry that this species has only been observed in the hobby and hasn't been named because we are all too concerned with killing it! I have been sharing with my biologist/aquarium friends and none of them have seen anything like it.
If you have had these guys or ever attempted a similar ID I'd love to hear about it.
Looks like it might be my guy:
Kinda like my guy but with detached polyps:

Hydroids?

Potential hydroids taking over
What was supposed to be a ‘clean’ tank building pod population has exploded with what appears to be a couple different types of hydroids. Can someone confirm? Any potential predators to knock them back? Options? The rock is picking up steam with what appears to be the same minus the...

Branching or Colonial hydroids?
Trying to confirm if these are colonial hydroid (Obelia longissima or Obelia dichotoma) or something else also is it safe to pluck away? That's what I been doing but have heard mix reviewed due to they being asexual. Lastly anyone knows a natural predator? I read some types of hydroid sting to...
