Resolved Can Anyone tell me what this is

Can anyone tell me what the little yellow thing is at the top of photo? I have 3 of them this is the larges that I could get a pic of .:-/

 

Looks like some sort of sponge or tunicate to me.

 

looks like a q-tip sponge to me! nothin to worry about

 

thanks for the ID

 

i concure lol def a sponge

 

I have a lot of those yellow sponges.. I like'em.

 

Looks like a Pineapple Sponge.

 

I'd say sponge too. Mine keep disappearing, so I'm guessing the fish/shrimp/crabs are eating them.

 

I'm a fairly heavy feeder and dose phyto.

Do you have any nudibranches or Angelfish? I know the nudis eat them. My shrimp, crabs, fish , and snails don't touch them.

 

I have a pair of Lamark's angels, but I haven't seen them "nip" at anything. Best I recall, they would appear and disappear before the angels ever went in...

I've not added a nudibranch purposely and haven't seen any after the lights are out, but it is possible one could have come in as a hitchhiker. I'm discovering new things all the time after the lights go out...
