Aside from the names being different can anyone tell me the major differences in these two crayfish as far as behavior, husbandry, etc.? I have a P. paeninsulanis now and will soon be getting a pair of P. alleni. I know better than to attempt to keep them together but is the P. paeninsulanis more aggressive than the P. alleni? The paeninsulanis is currently in a tank with danios and tetras and last night he apparently killed 2 danios and one tetra. I've had a P. alleni previously in a similar tank and there was no apparent aggression towards the fish so I am curious about the differences in the two. There is very little info on the web.
