Can they be in the same tank? I was thinking about buying 4 Blue Gourmais for my tank but I also saw the most in credible Beta. Will they go together. I know Bettas are very territorial but can the Gourmais go in with it. If not I'll have to get a Betta tank. I really want them to go together cause the Betta is a Beautiful Red with a yellow tint around it's fins and would look amazing in a tank full of Blue.
