Purple gonipora

[mmw64]

I have had this coral for two weeks and it has looked fine. Now it is deflated and has been for a few hours. Is this normal or is it unhappy? I have it lower in the aquarium in what I think is medium flow, medium light. Thanks.

Have u fed it? Some of this species require food, and can't survive with just photosynthesis.

So all polyps are retracted? Do you think you have a fair bit of plankton in your tank or do you skim it all out? Goni seem to prefer tanks with more life in the water to ingest.
