Does Anyone know what type plant this is? I have looked around and cannot seem to dig any thing up. It came in on the live rock and has took over this specific rock, and is starting to take over propogate to other rocks in the tank. From a viewer standpoint I don't really mind it and think it looks ok, but I also would want to stop somthing now if I knew it was gonna harm the tank. I plan on making the tank a mini reef (as money and time permit) right now it only has 2 fish and and some snails.
40lb live rock
Just finished cycling about 2 weeks ago.
Just looked at some aptasia pix, I am pretty sure that it isn't that. Unless these guys can look alot like plants. I am pretty sure it is sometype of plant. It is pretyt leafy. Try looking at the new pix if possible, make it a little clearer.
Looks like what we used to call Dictyota cervicornis, but it's getting a name change right now.
Either way, says your rocks came from a "dirty" environment and it's a bad one in the sense that it can take over.
Very small emerald (green) crabs can be used to control it.
Don't have an ID for ya, but the stuff comes on a lot of cultured rock. Grows like wild fire in good water and likes to spread. I had some come in on a shipment of rock I kept in a 30 gal. It'd loves NO lights. I'd do some weeding. You don't find much that will touch it for food.
yeah was confused by the "btw, no plants in ocean..they are corals... " comment. I will try and do some more research on it tonight if I can. I am almost certain it is some type of plant or weird algae or somthing. I just ordered a small army of Emerald Crabs though, so I will take you guys advice and do some weed eating and then let the crab army take over.
