paly is sticking out its tongue?

there is something coming out from the mouth of one of my palythoas? Its like a long, stringy tongue and is brownish. What is this and does it have anything to do with water flow?


Kinda hard to see exactly but these might help>.>>>>.>>>.

 

I don't think it has anything to do with your flow Crusty. What you are most likely seeing is either waste, or the coral is replacing those strains of zooxanthellae for better ones. How you can tell the difference is beyond me

 

cool. they all seemed to do this. every head was spewing this stuff out?

 

Yeah +1 to Tom, you might see the whole colony doing it at once. Unless you see drastic changes in color (like bleaching) or they stop opening it's probably just a natural process.

 

cool it sure freaked me out. cuz they are one of my favorite palys

 

I believe they may have developed sweeper tentacles. Read this; INDUCED DEVELOPMENT OF SWEEPER TENTACLES ON THE REEF CORAL AGARICIA AGARICITES: A RESPONSE TO DIRECT COMPETITION -- CHORNESKY 165 (3): 569 -- The Biological Bulletin
