I have a 30 gallon reef that's about 6 months old and ever since I moved my Gramma and clown from my 10 gallon( where the Gramma was out all the time) to the 30, he hides except to come out to eat, and I noticed the colors right where the yellow meets the purple that the scales are turning white, still eats, I'm just concerned that he's too stressed, I have a clownfish, cleaner shrimp, sharknosed goby, few hermits, and a few snails, parameters were all in good range, except for magnesium, it was a tad high(1500 with salifert kit). Everyone else looks happy and healthy, any info helps, thanks.
Happy reefing
