hitchhiker - not aptasia.. i dont think?
 

This part of the forum is always my favorite cause you never know what you'll find in your tank! http://www.thereeftank.com/forums/im...es/biggrin.gif

I've got some little guys in my tank.. started with only a few but they seem to have spread quite a bit over the last year or so. In my early stages in the hobby I had thought they were some sort of tube worm or feather duster or something. But now that I'm a more experienced hobbiest I believe them to be some type of anemone.

I'm pretty sure its not aptasia because they look a lot different and seem to not grow very large or be harmful in any way.

They remain fairly small so I cant seem to get a very good picture but the best way I can describe them is mostly clear in color but they have white dots at the end of their tentacles.

The closest picture I can find is this:

But its really not very close.. they are significantly smaller with no real visible color

it's a strawberry or ball anemone

not harmful?

No, not the small ones.

cool, thanks :)

not hydroids?

+1. Ball tip. Quite interesting

I have a cluster of these as well but like you said they are very small. Mine have not grown in size either. They're in a cluster. Def not aiptasia but I don't think they're what's in the link either as that one looks quite large.

thinking hydroids can have like a tubular skeleton

i wish i had a macro lens right now i'd take a picture. def not hydroids if OP and i are talking about the same things and i think we are. i quickly cruised melev's id site but saw no match.

Ball tip anemones and hydroids look very different. Hydroids sure seem to have that "hard tube" like appearance. When you **** them off and they retract it pretty much just looks like an empty tube.

The ball tip or Pseudocorynactis is a small anemone that won't cause you any issues. I have about a dozen of them. Some get quite colorful. Look at them after lights out, that's when they feed. They get to about an inch and a half when opened right up.

Mushroom actually;)

Theres many different kinds of hydroids not all have hard tubes or are brown in color :)
