What kind of coral

[Pdash]

So he was doing great up until my lights went out. Now he’s looking terrible again

It is completely normal for a euphyllia to close up at night. Cheers

Yes definitely looks like a wall hammer and they are harder to keep than the branching type, just make sure not to blast it with too much flow, I lost my 10 year old wall hammer due to brown jelly caused by too much flow. When its getting g to the end of the light cycle they will shrivel up and suck all the tentacles in so dont worry.

Corals do shrink when lights go out and after about 3,hrs of lights on fully fill to normal
