I just saw these today. Is it good or bad?

I may be wrong, but they look like hydroids.

Look like hydroids to me as well....

 

[maxwell50]

How do you get rid of them? After doing little research I believe it’s hydroids I got couple of them extending already

 

[reef lover]

Try manualy removing and epoxying over.

 

[maxwell50]

How bad are they?

 

[reef lover]

Imo...nuisance. .until they get out of control which happens quicker if you feed heavy...
