Would be my advice to.

If the fish you give are of high quality, they normally also contain enough vitamins, calcium, ... as the snake's should need. Fish that contain thiaminase should always be powdered with vitamin B1. I powder occasionally with a complete multivitamin powder, but certainly not all the time. If the snake is pregnant or a little one I powder more with calcium.
