I have tomatos, banana and avacado. Bread?
I fed them carrot haha i could use dog food
Not true, roaches will cannibalise (even dubia) and this makes them capable of harming a tarantula.
I just wont feed him for a little to make sure he’s hungry when they come up
Never heard of Dubai’s doing that. Other than eating roaches in the colony that have died. They tend to avoid protein rich food, because they are very susceptible to gout. I’m no roach expert though. But I’ve had Ts about 4 years now and yet to see a roach try to munch on a T. Not saying it won’t happen, but they are way less likely to than say a cricket or hopper that has much more powerful mandibles and do include protein rich foods in their natural diet. Some are even predatory. Obviously we don’t use those predatory species as feeders.
I sprinkle a few pieces of dog kibble in my colony to provide them some protein along with the regular fruits and veggies I feed them. I actually noticed their population exploded after I started feeding them kibble, but i sprinkle in a dozen or so pieces every other week, so maybe your friend fed them more than I do. I did hear from a roach supplier that too much protein will kill roaches as they don't metabolize it the same way we do, but a smaller amount is good to keep them breeding fast.
I may try that, but my colony is going crazy as it is. I feed mine rabbit pellets supplemented with fresh kale and sliced apples. They always bury themselves in the pellets and make short work of them. They are just shredded and pressed alfalfa.
I've heard of them eating nymphs, eating dead/dying/injured roaches, and even males taking chunks out of each other.
Anything above 50% protein causes them to die from uric acid build-up (cockroaches convert protein into uric acid and store it, they can then convert it back into protein when food is scarce, if they never run out of food they just keep storing it until it kills them), mature males are the worst affected as they're not growing or producing young.
Yeah, they're not as bad as crickets which will resort to cannibalism the second they run out of water or food but it still happens.
I switched the fish food I used in my roach chow (basically a mix of chick feed and fish food) without realising it contained double the amount of protein that was in the other stuff, dead MM red runners everywhere, nymphs and females were completely unaffected though.
