i have 2 red clawed crays who are about 6" long (without claws) and they live very happy together and share the same cave even though there are many hiding plasses and caves. they were aggressive to each other at first when there about 2" , but as soon as they reached sexual maturity they fell in love an mated and they live very happy together with there kids.
Is there a possibility that I could give my guy a friend then cause he seems so lonely now that he has no fishes to chase........?
