A Puzzling Question

[if_i_were_u]

I heard of an experiment that a friend of mine is doing and i would like to know everybody's opinion. My friend is gutloading crickets with colour enhancing fish flakes and feeding them to his savanna monitor and some other cricket eating lizards. And for his larger monitors he is splittling the backs of the rats he's feeding them and filling them with this fish food. I've seen some pics and some results up close and they look absolutely amazing. The main question i have is that, does anybody feel that this could have harmful side effects. Also does anybody think it would work? Thanks for reading.
