I'm not sure if there were on there because I'm really, really tired and not reading straight, but about the lady bettas..
- Don't house male and female bettas together, especially if you have them in anything less than 10 gallons; more often than not, they will hasstle each other and even fight. I know a lot of people think males and females would get along just fine, but really once the mating is done, they don't much want anything to do with one another.
- On that note... DO NOT breed your bettas unless you know what you are doing. Chances are your average pet store fish might not have the best genetics, and may be related to the mate you've selected if you're buying from the same store. They have TONS of babies, and if they hatch, you must take into consideration how you will home the fish, what to keep them in until they are mature, where to put all the boys once they get to an age when they will exhibit agression, and so fourth. Besides, too many female bettas have been beat up and killed because ignorant owners left her in too long, put her in when she wasn't ready, or simply chose a male that was far too agressive.
- Female bettas can sometimes be just as agressive as the males; most sites I've seen suggest keeping several females in a large tank instead of two in a smaller tank as they will pick on each other on a one-to-one basis. You really need to evaluate your female's temperament before getting her a tankmate, and I suggest removing both fish and changing the tank around before introducing the new one to help curb territoriality problems. And of course, if one of your girls starts getting tattered fins, don't assume it's fin rot right away and douse the tank in meds; see if the other female has been picking on her.
- Feed the girls a bit more when they are becoming swollen with eggs and exhibiting vertical stripes, especially if you plan on breeding. They are using a lot of nutrients to produce those eggs wether they use them or not, so that is not the time to be stingy on the food.
