the harliquin are too small,fast,and good climbers I love them as my pest but not for everyone
Panchlora Nivea=green cuban? those are fliers and not that large
he has trouble with seeing small objects
Discoids would be a good size and they are decent to handle
all Blaberus would be good for size but sometimes they can be harder to handle my Craniifers are almost impossible to handle,but not to many problems with Giganteus or Discoids just they hide most of the time
they like to hide most of the time but my favorite species that I want to handle more Is L.subcincta but even they might be too small L.Verrucosa gets bigger but Ive never owned the species
sorry for rambling lol long work day
