When I bought this live rock
The lady said it looks like this rock has a coral growing on it.
The location is 2nd rock up from the bottom left rate under the powerhead is a white and brown spot. Is is probably 3-4 inches.
Does anyone no what it is?
Thanks

its some form of encrusting coral...

What kind of lighting should I bye to help it out?

 

[theappe]

Im not sure. Since i dont know the ID i wouldnt be able to tell you. I have something similar to that that hitchhiked with my rock and I have 130w PC light and its doing good.

This is when they first came in. Now they are fully brown.

Those are Favia. I have the same thing on some of my live rock. It has little hair like tentacles. I think that Favia is closely related to brain coral. Looks good!

 

[brigbills]

Are you saying theappe has Favia or me or both

Could the first one be a type of Hynophora ?

 

[happyhourh]

Both of those corals look dead to me. Is there actual polyp extension?
The first looks like porites maybe?
I agree the second looks like a favia or acan.

 

[brigbills]

I have not noticed any polyp extension, maybe it is dead. I am new to this so not sure what to do.

 

[brigbills]

What can i do with this thing?
Thanks for your advise in advance.
