Identifying small white “tree-like” thing…

[AlaskanWaters]

Hello, long time reader, first time posting.

Can anyone identify what these things are on my rock? They’re pretty small, maybe 3/16” tall.

Are they ok to leave, or a nuisance?

Thank you!

Those look somewhat like hydroids...

Yeah, I haven't narrowed down the exact variety yet, but they're hydroids, most likely from the suborder Capitata - they might be an Asyncoryne species, but I need to do some more reading up on the families in the suborder to say for sure.

Hydroids for sure and may be thecate or Halopteris

Thank you all for the information! I’ll do some reading and see if I can identify the variety of hydroid. I appreciate it! Are they something I need to worry about eventually overtaking my tank, or not really an issue? No corals in my tank yet. Tank is officially cycled and I’ve got a pair of clownfish introduced. Still researching corals I’d like to add.

Hydroids when receiving a food source will multiply. Some sting nearby corals as some wont.

Hydroids? Don't quote me.

Got it. I’m going to see if I can confidently identify the exact type I’ve got here. Ultimately, I’d rather play it safe and get rid of them, but if it ends up being a harmless variety, I wouldn’t mind keeping them around. Thank you again

I have them as well did not and do not know what species but they have been around for a year and really haven't spread. Don't like hearing about stinging I am following this for sure
