What's growing

[Milwmarine]

I just noticed something growing

Tube worms/feather duster worms. Good guys.

Feather dusters. Cool!

Blow a little water at them. See if they close up.

Looks like feather dusters, just make sure the stalks are not brown or the feathery stuff is brown as those can be colonial hydroids and those are a nuisance.

And they usually won't retract when startled.
Hydroids jus look at ya;Bored

Do they grow

 

[saltyfilmfolks]

Yea they may spread. Some slow some fast. Some fade away.

They usually don't get big

Hydroids will usually stay small but create a colony and eventually overtake everything in the tank. The nuisance ones are usually brown and are pretty indestructable short of boiling ur live rocks. Ive used kalk, landscape putty and its like the stalks burrow in the rocks. Also dont try to tweeze them off as this will release more spores to spread. Hopefully its just feather dusters which im sure they are. Like saltyfilm advised--check if they retract.

Is this what you mean by brown tube/brown polyp? I was thinking these might be Aiptasia, but the entire colony pictured is about the size of a US dime / nickel. If these are the hydroids, is there a good predator? My peppermint shrimp ignores them (but it may just be a picky eater, right?).

Thanks,

Yup those are a hydroid. Putty and glue has always worked well for on those.
