Help me! I think I have a pregnant beta fish and I have no idea of what to do. First of all I don't have a filter in my tank so I have to clean it out every week or so, should I continue to do this? Becuase don't fish lay eggs? I want the new fish to survive. Once they are born should I seperate them right away or should I keep them all together? Please help me I have never had a pregnant fish before!
