[Shoal choice studies have revealed that fish have cognitive abilities to discriminate between groups of different composition. In this work, the role of social status (based on aggressive acts) of both the test fish and the fish in the stimulus shoals was examined because of the fitness-related consequences that group association may have for the test individual. Single angelfish of high and low social status (dominant and subordinate) were presented with a choice between two stimulus shoals… 
Shoal choice in juvenile angelfish (Pterophyllum scalare): effects of social status and activity
Results contrast with those previously found in this species when test fish preferred to aggregate with shoals of familiar subordinate conspecifics placed in small display compartments and indicate that angelfish take shoal activity into account when making a shoaling decision.
Shoaling Decisions in Angelfish: The Roles of Social Status and Familiarity
Past research has shown that angelfish, Pterophyllum scalare, are capable of discriminating between shoals composed of familiar dominant and subordinate companions, whereas they show no preference
Nutritional state influences shoaling preference for familiars.
Can angelfish (Pterophyllum scalare) count? Discrimination between different shoal sizes follows Weber’s law
Angelfish are able to discriminate between different quantities of conspecifics subject to a ratio limit, a finding that implies a fitness component in this behaviour similar to what has been demonstrated in higher order vertebrates.
Investigating the Effect of Familiarity on Kin Recognition of Three‐Spined Stickleback (Gasterosteus aculeatus)
The results show that familiarity does not overrule recognition based on phenotype matching or innate recognition, underlining the importance of these mechanisms, and lead to the assumption that individual recognition might play a minor role also in non-kin-based preferences for familiars.
Growth and social behavior in a cichlid fish are affected by social rearing environment and kinship
It is demonstrated that juveniles reared in a group grow on average faster compared to juveniles rearing in isolation under standardized laboratory conditions without predation risk, and genetic relatedness influenced social behavior in group-reared fish as well.

Shoaling decisions in three-spined sticklebacks (Gasterosteus aculeatus)—familiarity, kinship and inbreeding
Subadult sticklebacks preferred to shoal with familiar kin over unfamiliar non-kin, but inbred and outbred individuals had similar preferences.
