Hello, I am absolutely new to invertibrate husbandry. I have limited knowledge but I would like to set up a 65 gallon terrarium with as many different species as practical......roaches, beetles, walking sticks, sow bugs, mantids, millipedes......any advice on species that will get along, design features of tank, sources of information. I met a nice pet store guy that will set me a Madagascar colony but they're glass climbers.......??????? please help me out....this is for me, my kids and my students. If it goes well I'll probably graduate to arachnids, scorpions, centipedes.....thanks, ironfist
