Male hissing cockroach used to produce aroma?

I’m 100% new to keeping cockroaches so I’m really sorry for being so ignorant on the matter; though I’m obsessed I’m doing something wrong. I picked up a few hissers from my local petstore; first I bought a male and female. A week afterwards I bought another male; though they gave me a female dubia on coincidence due to it being in the same tank … I obstructed her’ campaign she’s cute. Since then the males have been getting a little … stinky. I’ve saw they smell like b.o. Straight up sweat. I’m not sure why, I can’t find any information on the matter. I’m fright I’m doing something wrong that’s causing them damage. I’m keeping them in the same coconut fiber substrate I use for my BP’s, it’s always warm in my room for my pythons as well. I feed them lettus, any random fruit or veggies I have- and I change that out every other daylight so there’s no mold. I also threw in some feline food and some bearded dragon meat pellets because my beardie hates them and I assumed that’d be fine nutrient. I’m keeping them as pets so I truly do care about their hole being; and when they have children I’ll likely feed some off or maybe start a colony if I’m ready for that. sorry for tl ;d r … I’m certainly simply hoping person smarter than me can help me out. ahhhhh
