I've had the puffer 3 weeks or so and he will only eat krill. He wouldn't eat the first 3-4 days then I got him to eat some krill. I fed him krill the next few days and have been trying to feed him silversides, clams, squid but he won't even try them. He chewed on a silverside once then spit it out but he won't even try the squid and clam meat. I have been letting him get a little hungry hoping he will eat these other foods but I don't want to starve him. Any ideas what his problem is? BTW, I tried adding some garlic and that didn't help.
