Hey peeps-

Nudibranch and get it out as grinder stated.

 

hes gone.....ill be on the lookout for more. thanx guys!

 

No problem,glad you got him.

 

I want to go one step above why to get them out.. you dont learn to why to get them out if you only told "to get them out". As a matter of fact, I didnt know what Nudibranch was until i did some research.

I got this from National Geographic

They are carnivores that slowly ply their range grazing on algae, sponges, anemones, corals, barnacles, and even other nudibranchs. To identify prey, they have two highly sensitive tentacles, called rhinophores, located on top of their heads. Nudibranchs derive their coloring from the food they eat, which helps in camouflage, and some even retain the foul-tasting poisons of their prey and secrete them as a defense against predators.

Nudibranchs are simultaneous hermaphrodites, and can mate with any other mature member of their species. Their lifespan varies widely, with some living less than a month, and others living up to one year.

 

What's not mentioned there is that most are specialized eaters, and only eat one of those things, not all of them.

 

All I know is there some harmless and alot of nasty ones and i don't know the difference,so that makes them all enemies to me.
