I have a big 75x35x30 glass tank but i dont know what roach to pick for it, there is already a layer of mixed : coconut fiber, clay, sand, spagnum moss; of course i will add many more things like bark, leaves and leaf litter and branches. Ive been thinking about Hormetica sp. or Therea bernhardti, but i still dont know what to pick.
