I just re-read your post and realized the glimpse is a good thing to the betta... such simple minds and pleasures. They seem to be doing fine now. One hangs out on the far side of the tank when he doesn't want to be bothered and then comes over to "threaten" when he wants to. The other one, "The Red Knight" just threatens most of the time. Obviously, he would be the dominant one!
Hey Anne, I told my husband the fifth would be the last... now I have six. (hee hee, we're such sick people). BTW, what types of tanks do you have?
