It appears the betta has no motivation either. Either that or he’s dead.
Found out that whilst I was gone, Luke was ~also~ feeding him (in addition the Mrs.). He had stuffed-beagle syndrome.
He's just pining for the fjords.
Poor betta... :-\ Maybe leave him without food for two-three days and see how he does?
Work betta 2 doesn’t get fed on the weekends and he’s doing fine (now that I’m carting in water from home), so they don’t starve very quickly.
