My gf has 2 axo's, one which to me looks like a female, shes had her for over 2 years now and a month or 2 back i got her a male. Their current tank is fairly bare, ih has a few large rocks which they can hide around and is in a fairly seculeded place where they dont get bright light and have a bit of privacy. Should the breed by themselves of should we be doings something to trigger breeding?
