Roach breeding.

[Truffs1178]

I have just setup a tank for breeding roaches in. It is my brothers Breaded Dragons old tank since he just got a new one. I don't know how big it is but I plan to breed Turkistan, Dubia, Madagascan Hissing and Lobster roaches in it because they will all breed in the warmth but have a few questions. There is a heat mat underneath 2/3 of the tank and a heat bulb which is keeping the air temp at about 31 to 34 degrees Celsius (89 to 93) out in the open but it think it is cooler under all the egg crates if they get to hot.

1. Non of these roaches will fight or eat other species will they?

2. Which of these species breeds the fastest?

3. Can I just feed them on dog food, oranges, apples, potatoes and other veggies or do they need more? This is what I have fed my Dubias on before.

4. Is the temp ok?

5. Which is the most nutritious or are they all pretty much the same?

I will be adding more egg crates and paper towel tubes for hiding spots. The background is only there because I didn't take it off when I got the tank.
