Valentino puffer not eating

[Frankenstinksdad04]

I have had my valentini saddle puffer for a couple years now, he has always been some what of a finicky eater. Sometimes he pigs out sometimes he's not real interested in food. I moved a little over a month ago and I don't think this fish has eaten at all since. All my water parameters are good, salt is good, haven't changed anything in the tank. He is in a 75 Fowlr tank with a yellow watchmen goby, marine Betta, royal Gramma, six line wrasse, purple dartfish, and a clown pair. Still using the same foods as always, his beak is not over grown. I usually feed once sometimes twice a day. I usually feed frozen brine shrimp, clams on a half shell, occasionally krill, occasionally frozen mysis shrimp, and shrimp. These are the only foods he has shown an interest in the past. All the other fish seem to be happy and healthy eating good. He is getting unbelievabley skinny. Does anyone have any advice on what I should do to help this little guy out?
