Yes, from what I've understood, since bettas are territorial, if they are established in a tank already and you add a community, then the betta will think they are intruding his domain. If you introduce the betta last, there is a lot lesser chance of agression!How did you introduce them ? Did you put the community fish in fish then betta ?
Thanks a bunch! He is so special to me!!!GIVE-ME-YOUR-FISH You are so lucky to have such a peacefull betta! Also, Great set up!
