Coral expanding upwards

[Luisreef]

Anyone know the name of this coral and why its expanding upwards. Does it need more light or is it fine I have never seen it do this before. Its usually puffy all around but today its polyps are reaching upwards. Its has some discolorashion on the green area as well. My kessil light intesity is at 50 percent.

The coral is an acan. Looks good. What type of lighting? How long have you had it?

The coral looks good. Mine get like that here and there. Did you recently and any coral foods to the tank?

No could it be a temperature problem since its summer the tank went up to 84 and I got back down to 78. But all my other corals look fine.
