I received a dogface puffer 5 days ago who is about 1 year old caught from the wild and is very portly (lots of body fat) for a dogface. However, I cannot get him to take any food. He acts and swims around normally, but puts his nose up to any food I offer. I have tried the following multiple times: Frozen Krill, Frozen Mysis Shrimp, Frozen Brine, Fresh Mussels, Scallops, Pellets, Shrimp Pellets. Not sure what else I should try or if I should wait it out. If I wait it out, not sure how long and then what?
