A few of these little guys started growing recently. What are they? Do i keep them? Thanks!

Hmmm... don't know.
They look kind of neat though.

I have them in my tank....never thought much of them...I don't think they are bad???

 

[ReefGuy69]

Do they retract or move when you or an object gets near them?

 

[Dragon Wrasse]

Mine don't .....they are brittle.

 

[ReefGuy69]

I wouldnt worry about them. unless they start firing lazors out at you.

Hydroids??? Cool, that's what they are.....very good, Thanks BHinAK.

 

[Snelly40]

wow, hydroids are wicked cool, i dont know much about them but i have read about them in Marine Invertebrates, great find

 

[boozeman]

still would've been cooler if they shot out lazers

 

[Snelly40]

haha, laser's would be wicked cool

They do retract when anything comes close, as well as shovel food into their center with each branch. I have at least 10 of these starting to grow from my rock. I was a little worried since they all started growing within the same week. I was worried an invasion was imminent and was going to be forced resort to my laser-firing coral species I have growing in my fuge. Thanks for the help!

I have these in my tank as well and they had spread into several areas. I do remove them only from the areas where they are encroaching on my corals, but leave the rest. They are cool!

Hydroids are very bad for a tank. They can sting corals and eventually kill them. One of my friends had to take down his 380 because hydroids kill all of the corals in the tank and completely took over the live rock. But those hydroids looked much different. And I have some of the ones that your talking about and they dont seem to grow nearly as fast.
