Advertisement I was just curious what you guys recommend for starting a dubia colony. How many T's should one own before starting one? I am about to have two T's again and then in the summer I will bump it up to three or four and a millipede or two, maybe (But I don't think millipedes eat other bugs). I also have a grass spider but I usually feed it small crix since it's so small. Should I just stick to buying roaches when needed or should I start a colony?
