Can anyone tell me how I know if my betta is female or a wild one? I bought what I thought was a pair of bettas, put them in the tank with my other fish and the male one died not long after that. Of course, I did not know I needed to keep them separate unless spawning, so that could have been the problem. But I just read on the website that there is a wild version that looks like the female only more colorful. And now I am worried that maybe I put two males together unknowingly. My "female" is solid royal blue. The pictures on here show only the pale females.
