I intend to introduce pellet food other varieties of feed to my new young aro (approximately 7 inches). I believe the fish had been fed on live shrimps and feeder fish at the shop.
I have not tried yet, but I suspect the fish would not accept the pellet food and market prawns so easily.
What methods can I use to make the fish accept new types of food? I'm thinking of starving the fish for a couple of days to encourage it to take the new food. If this method is used, how many days can a young aro (approximately 7 inches) go without food? I dont want to starve it to death

!
What other methods can I use?
Thanxs.
