I have a female dwarf gourami in my tank along with tetras. I did have a male dwarf gourami but he died a few weeks ago. No idea what happened to him? Had him for about 18 months, I change my water regularly and all the levels seem fine. All the other fish seem happy enough. So rather than replacing him I was thinking about gettng guppies? I know I can’t keep them with males but can I have them with females??
