Aww that's so sad! He was such a pretty color. I hope he changes back!
I think I figured out why mine has been that silvery color. When we picked him up from the lfs
all he had in the tank was a rock, nothing else. Probably stressed the life out of him.
I tried to take a picture of him but he wasn't being very photogenic today! All he wanted to do was hide his back end in the hole and open his mouth at me! LOL. I added a couple pictures of what I could get of him but he really didn't want his picture taken (not that I blame him!).
I've been giving him mysis and a bit of brine shrimp but when I use the feeding tongs I don't think he gets to it fast enough. I have to do a bit of reading on other ways of feeding for him.
