Five or so will do. I already have a group and I've heard that they become very aggressive towards each other unless you have 10+. The group I have are fine, but I'd like to avoid any potential problems. Let me know when they come in and roughly how much you think they will be. Any chance you can get some Cyno Afra Cobue as well? I have three, but I think they're all females. They're between 1.5" and 2" and haven't begun to show much coloring. I would probably only want one or two of those.
Thanks,
Brendan
