They have been known to revert back to live food only especially after stressful situations like moving to a new tank. Try getting him some live food. What size is the tank?

It's a 250gal i know the shark will get big and I've been told the tank is too small but I've allspice been told that a 180 is big enough I don't know who to trust I just hope a can make this all work out without loosening fish I'd hate to tell my friend I lost one for him not taking the best care of this tank hes pretty proud of it what type of live food would be ok for these two

Live silversides I heard work I would do to Manu guppies/goldfish they are fatty and too many could harm your guys and goldfish have a lot of parasites

Excuse wouldn't feed to many guppies or goldfish
