What is this

[newone]

Can someone help me and tell what this is?
It is not coral line allergy. Because it moves
around the tank. :notsure:

Ok ... First off lets understand something, Allergy's are the pollon and dust/dirt etc... in the air that cause humans to have really bad respiratory problems... Algea is something in the ocean that the fish and other marine life eat.... What you meen is is this Coraline Algea.... not coral line allergy...now that you know this we can say if it is moving around your aquarium it is NOT NOT NOT NOT NOT Coraline.... its probably a skirted limpet or a type of snail/nudibranch(slug)/or whatever else it could be... If its not muching down on your corals or eatting anything like coral or something of value LOL, then we can safly assume its a welcome inhabitant to your aquarium.... I hope this helps you...
