Very cool, welcome to the wonderful world of roaches! Your dubia look great. I was just like you, when I made the switch I loved watching my roaches and found them very interesting. I love to check in on my babies, see how much they are eating and especially see all the new baby roaches scurrying around. It is so much fun raising these little critters. Plus Spike really, really loves his roaches - YUM!!!
You will find care info on Jason's sight,
http://www.theroachguy.com He has all the info you need to set up your colony and keep them healthy and breeding, it's all at your finger tips right on his site.
Now that you've made the jump to roaches, I suggest you go to
http://www.theroachguy.com and buy another 150 mixed dubia to give your colony a bump. You can check out my recent posting here:

Where I outline how my new colony has done since starting it in May and it is now ready for me to begin feeding off of. To get to where I can now feed off them, I started with 55 adult females, 20 adult males and 150 mixed from theroachguy.
Good luck on your colony, and please don't start feeding off them until you get a handle on what it will take to get a breeding colony going, you don't want to waste the money you've already spent on feeding off too soon
Keep asking questions on this forum, all the roach people here will be glad to help.
