Starfish!!

aiptasia are a type of anemone they filter the water but they also have a potent sting and reproduce really fast, they can damage corals and are difficult to get rid of if not controlled they can easily become a plague

That being said one of the LFS here (i no longer go there for other reasons) actually has a fuge full of them, literally, they actually plumb water through them for their filtering abilities

 

Interesting... I have a couple in there right now... I will watch to see what happens... They are SUPER tiny though.

Thanks!

 

i wouldnt want them in my display tank. because once they get a foothold they are a headache to remove. seriously, if you can, get rid of them now.

 

+1 on this comment , they are very aggresive and reproduce amazingly quickly

 

If the "starfish" is white and soft looking, it is an asterina. If it is about the size of a dime and is made up more like a regular mini starfish these guys will eat your coral if you have any! here is a good read with pics on these guys! GARF predatory starfish 11/25/01

 

on this subject of stars. recently we found at least a dozen tiny brittle stars. ive got 4 "adult" brittle\bristles. would these adults have reproduced? or are these little guys just hitchhikers? their bodies are the size of a pinhead, and their tentacles wil stretch out about the size of a dime. and they definitely arent the asterina. and apologies if ive taken over this thread, just thought it could be appropraite here in regards to star talk.
