Need ID's

Hi people! I need Id on couple of things
The tank is about 5 months old it the 2 fish inside are clown and blue demsel.


Not sure about the plants,Some kind of worm?and some small egg sac?

 

Howdy there. Sorry but the pics aren't very clear. If I see things right, in the second pic, that might be a colony of sponges. Are they white to grey in color? If so, might be. Can't tell anything from the first and third pic.

 

thanks,well its some brownish plants and starting to get massive green algae on live rock ..and the small around thing is white..The worm is tube like and round.seems it doesn't like the light alot...

 

that is a peanut worm

 

Hey! I have the same thing you have (1st and 3rd pic). The first picture, i dont know what type of algae it is, but it sure grows fast. And the 3rd pic, I posted a thread asking what it is and people said its a peanut worm and its harmless.

 

Thanks everybody..Does anybody know about the plant thing?Also more information about the worm and egg sac looking thing?
