Hi Garfield
Here are some basics I use with all my roaches:Gromphadorhina portentosa, Blaptica Dubia, Blaberus fusca and Blatta lateralis
1) Ventilation - they can fart themselves to dead if your colony is getting big. I Cut 2 Huge squares out of my lid and hot glue, very fine stainless steel mesh over the huge squares, this also ensures that no mites or other insects will get into your colony.
2) Heat is applied to speed up the metabolism of your roaches, and to keep them safe in winter
3) Water - A huge water bowl filled with some pool filter sand that has been pre-washed. This also allows the nymphs to drink from the water, and it also helps with the humidity.
4) Dry-mix food - 1 part oats, 1 part bran and one part liquidized (powdered) "montego classic puppy mix"
5) Fruits - Fruits are only fed once in a blue moon, but when I get my hands onto oranges, I will feed them cut up wedges with the skin on. I place the fruits in a separate container, and feed them until they are bored of eating oranges. Some claim that the Vitamin C boost in oranges helps them breed more, but I have not come on a scientific paper proofing that it is true, I just know my roaches enjoy their oranges in winter. Carrots, apples, banana etc could also be used. Trust me the larger your colony the more work it is to also feed them fruits.
So there will always be dry-mix and water in my containers.
Error shooting:
1) Deformed wings after molting - not enough moisture is available in the container. Solution add more water or a closed container filled with flower gel ball crystals. When the gel balls decrease in size, just drop it back into a bucket of water, this is for moisture purposes only.
2) Dying roaches - If you have medium to small roaches die, check for the obvious: Are there enough water, enough food are the container cold to the touch. If the above is in check then I would check under the food and water bowls for any mold, if any is found then it is time to clean out the container, replace the egg flats, remove the Roach crap and eggs/ molts from the bottom and keep it in a small container as you might have more nymphs hatching. Fruit flies could also destroy your colony, if any fruit fly is found in your colony, then try and make sure your lid is secure and air tight every time.
If anyone needs advice please post your questions in this thread?
