African Butterfly fish not eating

I got a butterfly fish about 2-3 weeks ago, and after eing in the tank for about 3 days he would eat live crickets, he ate about 5 or 6 crickets over about a week and a half, Last time I put crickets in there for him they stayed in there so long they died, so i took them out. I've tried to get him to eat bloodworms, flakes, but for the past 5-7 days he hasnt eaten. please help

Haven't had that issue before with the one I had. He definately was a piggy that's for sure. I'd always enjoy when a bug or simple food hit the surface. Lightening fast! Like stink on ... well .... LOL

Can you tell if he is pooing? Maybe too much grub and hasn't processed yet.

he finally ate another cricket... I stuck 1 in there, he looked at it for a little bit, sat there, finally I remembered to turn on the light. that's when it clicked for him, IT'S FOOD!!!!

Yay!

You can also try meal worms,Make sure you cut bite size,You a razer blade.
The pieces of meal worm will stay on the surface.
