reef tank what is it

[dbest1]

i have some things in my reef tank that i dont know what it is maybe some one out there know what it is this is pics of them/

 

[Atarax]

the pics are a bit too fuzzy to tell for sure. but the pic on the far right looks to be sun coral or maybe even some sand polyps. about an hour or two after u turn out the lights run back and check to see if the polyps are out. they should be light yellow to orange in color if it is sun coral..
the two bottom pics look to be of a green macro algae that we call "dead man's finger"

 

[dbest1]

it looks like it has teeth in the hole and it moveds in and out and if you touch it it will close up. so what is it

 

[chrisdef15]

No idea get a better camera. Teeth?? Sure its not like crabs legs or something??

Really hard to tell from the pics. Maybe a sun coral and the other looks like some type of zoanthid.

tunicate? stick your finger in and see if it bites...j/k!!! haha. with my luck it would be some venomous sea creature and i would blame myself for your death, resulting in a crappy home life for me.

tunicate. harmless. and very boring. lol

I'm going to go with tunicate or maybe even one of the myriad species of cup coral. It's really hard to say for sure. If it is a tunicate the whole knob is it's body.
