Yay or nay?

I think i read it somewhere it may cause constipation?
 
Have tried it years back but my rays dont liked them. They sometimes eat them and i see mealworm body on their poo - seems they dont digest well.

On another note, Im trying black soldier fly larvae now but they seem to float so my rays have a hard time eating them.
