Trying to identify this rapidly spreading saucer and cup shaped object. Two pictures are included one of the outside and one of the inside. It is brittle and breaks up easily like a potato chip. It starts off deep red in color and as it gets older seems to go to a faint yellow. I would like to get this ID'd as I am moving all my live rock to a new tank and want to see if this is helpful in any way or if I should be looking at getting rid of it (and the steps to).

I'm not 100% sure, but I believe it is a type of coraline algae

Nice thanks for the reply... I have been having alot of problems keeping the calcium up. If it is coraline, I am guessing that I should keep it.

Looks like is could be Padina sp? Is it soft or hard to the touch? Brittle or moveable?

Just heading to work and may not repond back for a while.. but it is hard to the touch and brittle. Very much like a potato chip. Thanks again all for the replies.

Not Padina then...maybe it is a type of coralline. Never seen it before though. :D

I really don't think its coraline, I had something very similar grow on one of my zoa colonies. Its a little more fleshly than coraline and it grows a plate right over the polyp killing it. It's sweet looking just watch out I know the stuff I had grew fast and was a PITA to remove.

It is a type of macro algae. Not sure of the name thou. It is nice but can take over your tank. I just pulled a bunch out of my nano.

Peysonnelia spp? Not sure what the texture of this stuff is, but it reminds me of the stuff you have.
