So had this guy for a few months and everything was good, he lived with a Huma Huma but the trigger jumped as I forgot the lid one day and since then the puffer has quit eating, he was eating about anything following the Huma Huma, mainly mysis and rods frozen foods. He is in a tank that had quit a few creepy crawly bristol worms and they are all gone or I don't see them anymore. But at nite, I can see him patroling looking for them but at feeding time and for the better part of the whole day he just chills in the rocks out of sight. Any ideas on what I could try and feed him to snap out of it? He never messes with the snails, crabs or the cleaner shrimp in the tank and hell I even saw a peppermint shrimp that I thought was long dead a few days ago, ideas?
