I have a female betta named Butterfly, and I think she is ready to mate. I'm not exactly sure what are all the signs, but she has this white dot under her belly and she looks really swollen. Also when we put her tank next to our males (sorry he just passed away this morning, so I have to get a new one), her gills flare out and she flaps her fins really fast. DOes this mean she is ready to mate? I also have another question, if I choose not to let her mate, will this harm her in anyway, I just don't think I'm ready for that type of responsibility of more babies in my house? I'm new to this Betta thing.
