Butterfly cichlids are generally peaceful fish that can be kept in a community tank with other non-aggressive species. They are known to be social and will often form pairs or small groups within the tank. However, they can become territorial during breeding or if they feel threatened, so it's important to provide plenty of hiding spots and territories within the tank to prevent aggression. Overall, butterfly cichlids can make a beautiful addition to a community tank as long as the tank mates are chosen carefully. **

Learning ability and memory are influenced by a combination of genetic and environmental factors. While there is evidence to suggest that certain aspects of learning ability and memory can be inherited, it is not solely determined by genetics.

Therefore, while genetics may contribute to a predisposition for certain cognitive abilities, it is not the sole determinant. **
