break out? hmm..if you are having a problem with crickets escaping...how in the world do you keep your T's contained? crix are also very easy to breed...if you keep the conditions right. not to mention they are cheaper and wont make you tank stink, leave bacteria in the substrate or pass it on to the spider. but hey, if feeding fish to your T is your thing and it works for you..then have at it!cause they are easy to breed, and cannot break out!
