My female Betta, Sasha, is not a year old but i wanted to try and mate her with my male betta, Titan, (both veiltail bettas). When i show them to each other, Sasha will show her vertical stripes. But when i take a cup, put her in the cup, and place that cup in Titan's tank (and bubble nest), she only shows horizontal stripes. I'd keep her in there for about an hour or two and she will only show horizontal stripes the whole time. she does not flare back and she is in a submissive stance but has horizontal stripes. Can she still mate? is she getting too old for her to mate? (i mean she is probably a couple months old). any suggestions?
