Could someone help ID these?

Could someone help me ID these?

Just very curious about what they are

Picture 1, Picture 2, Picture 3

 

Can see them the links are messed up

 

cool web cam shots mate

 

1) hydras, little jelly fish like creatures that will come and go.
2) some kinda macro algea
3) um... there is abounch of stuff in there. I would say what your talking about is the branch like thing in the middle. Im not to sure what that is. Kinda looks like some kinda tube worm, but in not sure.

 

I must say I dont think the first picture is hydra, however I am not sure what it could be. Are we talking about the star like things or the yellow thing? Hydras however dont match the looks of either of them. Pic two kinda looks like a meaty algea. Pic three, well I dont know what you want id from in this pic theres alot of things in it.

 

Hydroids is what Birchell meant, I think.

Staurocladia

Looks like there's a red flatworm (planaria) right next to it too. Picture 3 has some fan worms in it and what looks to be another type of macro algae.

 

Thanks for the help. I'm talking about both in picture 1, the yellow one mostly, I think it is a slug of some type. Picture 3, yes I'm sorry for the shot, what I mean is the tree looking thing in there with the tube worm. Kinda look like a little tree and at the end of the branches are little feather duster looking things, they pivot with the water movement, very strange looking. I will try and get a better shot.

 

The yellow thing is a flatworm (planaria). Hopefully, you won't have an outbreak because they can become unsightly if they reproduce en masse. I still think that the third picture is some sort of macro algae with feather dusters growing on it but a better picture would help.

 

Thanks for the help on the ID

Thanks, the hydra's are not so prevalent now. Only saw the one flatworm, and the 3rd photo is of the tree looking thing, I will post a better photo Friday afternoon.
