I used to have an Oscar that loved the sticks. One time I wanted the other fish to get some of the food too, so I broke the sticks into small pieces and then Oscar would not touch them.
I am using up the last of my Hikari food sticks but once Im done, I wont buy them again. I find them messy and and they are also expensive. I can get NLS at cheaper prices and I think its a better quality food.
