Anyone ever see one o these? The blue things surrounded by off white skin/skeleton. sorry about the blurry picture. the blue parts open and close sometimes.
We definitely need a closer picture. If I were to take a wild stab at it, I'd say that it is a colonial tunicate, judging from the fissure like valleys in it.
this is off your question,but i was wondering if you could tell me what kind of plant that is in the pic? sorry for asking but i have that growing in my tank right now at a fast rate,sorry to ask in your post.
