Thanks for the reply. I think they are male and female and have been together for about a year with no problem . I will separate them as the female has had a few bites .
Hi. I have had two uarus for about six months .They are about 6 inches. They have been fine together until the last couple of days. Now they are biting each other quite badly . Have read that this could be the start of breeding .yet worried that they are going to hurt each other . thanks in advance.
