Prasinus question ?

Having a small colony of Prasinus that i am currently working with i am trying to vary their diet as much as possible , being insectivores as a rule in the wild i am offering crickets , roaches , etc.. and they are takin with vigor ...
But mine also love fresh fish does anyone else feed fish and fish skin they absoulutely go crazy for this , i am thinking that the amino acids in the fish are great for them .
It is also my opinion that Green Trees will kill and eat anything it can over power so it is my opinion that more than insects are takin in the wild !
