I have a large orange and purple ric Yuma in my tank which was doing well up to 3 days ago...  After a water change my lights were accidentally left on rather than going through their normal schedule and dimming to black at 8pm. I noticed at 10:30pm and turned them off but since then my Yuma has been balling up more frequently and appears shrunken when extended!

All my levels appear normal and all the other corals in the tank are fine including 2 ric Florida’s.

Any advice from yuma owners with similar experience would be great.

I think it'll be fine,  when mine bleached from too much light it was obvious straight away (it shat out its zoox, went totally white and shrunk to about a tenth of its normal size).

Pleased to say the yuma has recovered.
