Since you're going shopping anyway, you could pick up some Wardley's liquid fry food/Hikari first bites. Long shot, but if he's on the way out anyway ...

Have you been to Victoria?? :) Tough enough to find flake food.

I know its a bit late but fish are supposed to love Doc eco eggs. Might be good to try on next fish if this one doesn't make it.

The ones I mentioned are freshwater foods

PetSmart, Creatures, A Pets Life, Pets West ....
Someone must carry fry food

My only real LFS is J&L, so kinda hooped.

I've moved this guy to the DT in hopes he can forage for stuff, black worms didn't even get a second look.

Lesson, don't buy fish that isn't eating yet, even if it means you don't get the fish at all.

Maybe you'll get lucky and him seeing the others eat will help

sit in front of the tank and eat a baconator, maybe he'll get hungry

I don't know what that is, but I don't think I eat those lol
