Coral Help

[beebedl]

I bought this coral awhile back and forgot the name and was wondering if anyone knew what happened to them. When I bought them,they was neon green and the last 6 months that I have had them in my tank they continue to be a brownish color. In very few small spots they are brighter green. Any ideas and what the name of these are?

Looks like star polyps. Is/was the base purple? If the color is not like it was you could have lower par lighting, different spectrum of light that is not showing the same colors or you could have higher nutrients in your tank.

Yes the base is purple,Do you recommend to put them in higher or lower light possibly?

If it is browning then I would try to give it more light. I should add try to put it in similar light to what it had before.
