I'm not sure if this is the right area to be asking this question. I have some things that are on the rocks which to me seems like drab coloured small anemone. There are several. What is this? Very few tentacles tho. I have many small hitch hiking duster worms and I'm sure these aren't worms. I can't find my cell phone chip at the moment so can't take pics. Anyone has any idea? Thanks

If these are anemones, can clownfish host them?

It sounds like they are either Aiptasia or Mojano Anemones, both of which are invasive and neither of which a clown will host. But, pics help.

Thanks, I googled aiptasia and mine look exactly same. Seems like they're good for nothing. They compete with corals for food, etc.

Peppermint shrimp eat Aiptasia

peppermints eat aiptasia most the time. BUT they will also eat all your mini dusters

They say those shrimps can harm small invertebrates also. I'm going to try the needle thing. Not sure where I can get needles tho.

your lfs may carry them, mine does at least...you could also go to a vets office and ask for a non-needled syringe(don't want them to think your a junkee ) and they'd prob. give you one as long as you let them know you need to "medicate" a tank inhabitant

Pardon my lack of knowledge. Don't you need needle to inject something into the anemone? Is it good enough to just spray the liquit around the anemone?

I've bought syringes with needles before for injecting MEK into acrylic joints, you can get them at any pharmacy. Yeah they might have thought I was a druggie, so I went to a pharmacy I would never otherwise go to. Its not illegal to buy them and I'm not worried about what some random rite-aid pharmacist who I'll never see again thinks...
