sponge? ID please

[reefy]

I felt in love at first sight, Ron from King Ed Pet charged me an arm and a leg for it. I bought it without knowing what it is. I saw it at the display tank, and boom, its mine... I am pretty sure its a type of sponge or a filter sorta thingy (I know is not gonna last long neither). its light blue. size is perfect for my tank (3" tall 2" around) I asked Ron what it was, he was like "ahhhh its a sort of LPS" with a heavy korean accent... I was like...sure buddy... just bag it for me please. I make sure that he didnt expose the coral to the open air, he had a dirty look at me when I said that. he thinks that I was crazy or something lol..
