dubias a deff the way to go... they don't smell.. they're really not as gross as most roaches go... and beardies definitely love them and they are better for them then crickets are
SRK has the lil starter colonies if you wanted to get only a few.. but it would then take a good amount of time for them to grow out ( we got 10 from them a month or so ago and they just finally got into their adult stage and should hopefully be breeding soon). I definitely thought that we only had 4 from those 10... but somehow the others just were realllllyyy good at hiding :p
if you go to www.theroachranch.com you will find some good ones. Hes in Fall River I believe (we've only gotten them shipped from him) and they arrive pretty much the next day. We've never had a single one die from him and they are great breeders and Ian is a really nice guy that will anser any questions that you have.
