I have a pastel ball that I have had since 1st week of september finally got him to eat on Oct 15th I had to place him and a hopper in a brown bag in his cage I have had to do this twice now I left the hopper in the tank for about 3 hrs nothing put in bag took it in about 30mins. Will I have to feed him this way from now on? Or will he grow out of it. The Ball is in a 10 gallong tank with 2 small hides a water bowl and a humid hide temp around 87
