fippy: you'll get better results if you post your own thread. Go to the main page for the betta diseases, and click on new thread. I reccommend antifungal medicine, AQ salt, and 100% water changes. oops. I guess I'm the second person to say this...
Kayla: I have a male that is just plain lazy. Mostly he just lays at the bottom, except at feeding time, or occasional exploratory jaunt. When my male is put into the spawning tank, he is gentle & a good attentive father. I wouldn't worry about it, unless he's breathing hard or not eating.
