Male hissing cockroach used to produce stink?

I’m 100% brand-new to continuing 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 neighbourhood petstore; first I bought a male and female. A week subsequently I bought another male; even though they gave me a female dubia on coincidence due to it being in the same tank … I remained her’ justification she’s cute. Since then the males have been going a bit … stinky. I’ve noticed they reek like b.o. Straight up sweat. I’m not sure why, I can’t find any information on the issues. I’m fright I’m doing something wrong that’s causing them harm. I’m keeping them in the same coconut fiber substrate I use for my BP’s, it’s ever warm in my chamber for my pythons as well. I feed them lettus, any random fruit or veggies I have- and I change that out every other date so there’s no mold. I also threw in some cat food and some bearded dragon food pellets because my beardie hates them and I assumed that’d be fine nutrient. I’m keeping them as domesticateds so I actually do care about their well 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 genuinely just hoping someone smarter than me can help me out. ahhhhh
