How many market prawns can be fed to a silver aro?

  • We are currently upgrading MFK. thanks! -neo
I feed my ~20" aro every other day. Keeps him hungry. If I feed him and he doesn't hit the food, I will fast him a couple days.
My aro shows no interest in eating, keeps always strolling in the top surface area. Not sure what is the problem, no ammonia nitrite or nitrate in the tank. Shows no interest to eat MP , superworms or pellets.
 
I fast my Arowana once or twice a week. Otherwise he sticks up his nose at anything he is offered and the greedy Oscars get it all.

Variety is good for them. Don't give up on the prawns altogether, but also offer different types of large floating sticks and pellets. Insects such as crickets, mealworms and nightcrawlers are great too.
Tried with a variety of food, pellets MP superworms, aro is just showing no interest to eat.
