Bettas, are great fish. I now have 4 after rescuing 2 the other day. I have to say that i am glad that you are going to get info on them before getting them. Too many people think that they can live in a little cup and be happy. Mostly i think they need alot of love and good water, and of course food. I feed mine Hikari Betta Bio-Gold Pellets twice a day. I also feed them bloodworms. Usually if you keep their water in good condition, and feed them properly, you dont have many problems with them. They also like to have places to hide, adleast all 4 of mine do. Mine also love their plants, i think it makes them feel more at home, since they do come from rice patty planes. Good luck on your reading, and let us know what you get. Sandy
