I was wondering if different Procambarus species can live together, i am not worried about fighting i just dont want them to get sick. Also could they make a hybrid maybe Procambarus Alleni with a Procambarus Clarkii???????????..............
I had 4 or 5 crays living together, all the same species and local.
They were some fights but nothing major. They all eventually got eaten by my Oscar tho.
The one thing you might want to be careful of is babies, I remember looking it up at one point and they can have lots and lots of babies...
