That chart is too vague. Acei are a pseudotrophues species along with MANY other species with all types of aggression levels. Demasoni will be aggressive to anything that looks like them and vice versa. The afras will most likely be aggressive towards the demasoni. The numbers will spread out the aggression but you still run the risk of fighting between the males of these species. When it comes to demasoni it's best to pick a species that looks nothing like them for tankmates.
