I am pretty sure I could find info on the forum about this matter if the search feature would work properly, but I'll harass you guys some more cause I really want to know!!!
I saw a lot of people stating that dog and cat food wasn't good for roaches, and specially for the animals you feed to roach to. Is that true? I would really like to have facts instead of opinions please!
What about fish flakes? Is that good?
I have dubias btw if you couldn't tell I am currently feeding them carrots, broccoli, lettuce and mostly any fruits and veggies I buy, dog/cat/fish/rabbit food!
Thanks in advance!

Personally, I have a mixture of all three (dog, cat, and koi pellets because they were all free). I've noticed certain species pick out different pieces first though. I do not believe it's bad for the 'roaches since they are omnivorous, most anyhow. The only thing I can possibly think of why it would be dangerous to feed the ‘roaches off that have been eating this food is that melamine deal that happened quite a while ago. I’d ask myself a few questions if I was concerned: WHAT am I feeding the cockroach to? What is the natural diet of the predator? What do the other possible prey species feed on in culture and would these be a safer alternative? What other types of food besides ‘roaches and alternative feeders would whatever predator I’m feeding eat?

Raised roaches on them plus fruit and veggies, roaches lived well over a year after maturity so it cant be that bad.
