9 inch Silver Arowana stops eating for Week.

[Brix Pacis]

Good day fellow fish keeper,.i just started keeping an silver arowana a month ago and it grows 8-9 inch already, i keep it in 150 Gallon tank with a 2 angel fish and 1 cory catfish for cleaning the tank.,i feed the arowana with super worm, but with the past 5 days it only eats in morning and refuses to eat in the evening, the big problem now is the arowana wont eat anymore, i constantly change 25% water change every other day.any help. thanks in advance

PS: i tried feeding a Minnow Feeder which i breed my self it wont even bother eating either.

It's going to swallow the cory catfish and probably choke on it due to the pectoral fins. Plus, cories need to be kept in schools, and they do not clean aquariums. They eat food, not poop. You need to remove the cory immediately, and probably the angelfish as well.
The arowana also needs a variety of food, not just superworms. Try frozen krill or bloodworms.

Krill, earthworms and crickets might entice some more eating. My silver quit taking earthworms, spoiled with the krill.
