How to get rid of Hydroid Jellyfish

ReeVo · 04/16/2011, 05:49 PM

Hey guys, i have a 50 gallon cube thats been up and running for about 2 1/2 months now. Everything was fine for the first month and a half but then I started getting these strange white dots on my glass.

I did some research and found out they are Hydroid Jellyfish. I wish I can take a picture of mine but my camera cannot focus on them very well.
Here's one I found one google.

I've had them for a month now and they are just not going away. I've read they will just disappear, BUT THEY HAVENT!

What can I do about this problem guys.
I think they wiped out my copepod population too because I dont see any of them anymore.

Please help me.

I'd like to know the answer to this too as I have tons! They don't really bother anything but they are unsightly on the front glass

: I tried some zaptasia as I was zapping some aiptasia and that seems to work... but there are WAY too many to do this to.

bump, These things are driving me crazy. Are they supposed to go thru some sort of cycle and die off or am I stuck with these things.

They should die off in a month or few

I had a few in my tank when I set it up. They are all gone now, about four months later. All I have in the tank currently are clowns.

I seem to always get those when I first setup my tanks but they always are goine after a month or two.

Sweet, ive been seeing them for about 2 weeks now.

I have hundreds of them. Hoping also that they reduce in numbers some day! I scrape them off, within a couple days they are everywhere.

Well ever since I posted this thread, my hydroids are slowly going away. I used to clean my glass everyday, and have atleast 20-30 hydroids on ever side of the glass. Now I have like maybe 1-2 every week. So I see them dying off slowly.

Also, a few of my fish even eat them every now and then. My wrasse, chromis, blenny, and anthias will pick at them when I feed.

I agree with everyone else. When I first set up my tank there were hundreds of them. Even real tiny ones so I thought they were breeding. But 2 months later I cannot find a single one. My clownfish would try them and spit the back out, my bangaii never touched them, but they are gone and that's all that matters now.
