On a scale of zero to five based on my experiences:
"Hisser" Species- 3
They don't usually harm one another but do battle for territory.
A. tesselata - 4.5
They are bad wing biters but some dog food and plenty of space help, but slowly their wings will disappear.
B. giganteus - 3
I don't have a very high density of males to it really isn't that bad but I have heard that they can be fairly aggressive.
E. posticus - 4.5
Like peppered, if they have lots of space and protein they are alright but a perfect male specimen will not last long in a cage without some damage.
G. bisannulata - 0
I have a low density of males but haven't seen damage on them.
G. lurida - 1.5
Again, I have a low density but have noticed a little nibble hear and there I haven't boosted these guys protein yet so maybe that will help.
B. lateralis - 0
Have quite a few of these guy's and haven't seen any male/male aggression there is food aggression between all the 'roaches without regard to sex of size.
N. cinerea - .5
Have quite a few of these guys and have seen very minimal damage even though they do chase around each other.
These are all species that I own and are (mostly) winged. In those sp. that have wings damage rating is assessed by rate of wing biting presumably by males. Other species I own that do not have wings it's hard to assess damage and aggression between males so I didn't even try. Aggression is affected by many things such as male density, female density, food (types, quantity available), temperature, and amount of surface area in the cage (increased or decreased hiding spots and territories). I hope that with this information nobody is playing a six legged version of Michael Vick. Maybe some others can add to or argue against this post.
