@Zenzo @Irene thanks for your help. I will keep an eye on the aggression and add some more rocks,line of sight breaks, and be sure to get vegetable based foods in there for the mbuna. I have them in a 125 it will be exciting to watch them grow. I am subscribed to both of your channels and have watched almost all of your videos. I sure wasn’t expecting you guys to be the ones responding… pretty exciting!!
