I guess you could try them together however as livingart said they are aggressive when spawning and for territory, however, as most know Kribs can be also :lol: :lol: Yet the Brichardi can pack a bit more punch... I certainly wouldn't say Brichardi are fine in a smaller fish community tho with tetras etc, I have heard of someone getting away with keeping one, but more than one hmmmm :lol: Brichardi live in a tight knit family unit and work together raising young, so if you were to get a number of them, down the track once everything is settled and they are breeding, your Kribs could end up looking a bit battered or cowering in a corner... Also lastly keep in mind that your Brichardi do prefer somewhat harder water conditions.
