Shoaling behaviour provides antipredator benefits that rely, to some extent, on a high degree of phenotypic homogeneity between individuals within the shoal. Therefore, fish should have the ability to discriminate between potential shoalmates, choosing to associate with individuals of similar appearance to themselves. We studied the effects of a single phenotypic character, body coloration, on association choices made by black and white mollies (Poecilia latipinna). When given a choice between… Expand
Innate and Learned Shoaling Preferences Based on Body Coloration in Juvenile Mollies, Poecilia latipinna
TLDR
These results show that P. latipinna are capable of the behavioral plasticity that has been demonstrated in other fish species, and that early experience affects the impact of body coloration on shoaling decisions in this species. Expand
The Effect of Shoal Size on Patterns of Body Colour Segregation in Mollies
TLDR
The results indicate that mollies actively discriminate between shoals on the basis of both body colour and shoal size, however, body colour segregation appears to have a stronger influence on shoal choice. Expand
Within-shoal phenotypic homogeneity affects shoaling preference in a killifish
TLDR
It is demonstrated that fish might associate with the shoal that maximizes phenotypic homogeneity in body pigmentation, irrespective of their own phenotype. Expand
The effect of body coloration and group size on social partner preferences in female fighting fish (Betta splendens)
TLDR
Results suggest that association choices in B. splendens females are strongly affected by both body coloration and by group size. Expand
Recent social environment affects colour-assortative shoaling in juvenile angelfish (Pterophyllum scalare)
TLDR
The results suggest that angelfish use body colouration as an intraspecific shoaling cue and that learning, in the form of recent familiarization with a specific colour phenotype of conspecifics, can affect colour-assortative shoaling preferences in this species. Expand
Shoaling in juvenile guppies: The effects of body size and shoal size
TLDR
While juveniles at each age shoaled, only 50-day-old fish demonstrated the shoal mate discrimination seen in adult fish. Expand
Within-shoal phenotypic homogeneity overrides familiarity in a social fish
TLDR
It is shown that social preference based on familiarity can be completely reversed when phenotypic homogeneity is introduced as a criterion for group choice, and this finding suggests that homogeneity in body pigmentation may affect shoal assortments more than previously considered. Expand
Assessment and assortment: how fishes use local and global cues to choose which school to go to
TLDR
It is found that focal fish were able to assess globally mixed shoals composed of individuals of different body–length classes, preferring to associate with shoals where the majority phenotype matched their own, and both local and global information play an important role in mediating assessment and shoal choice in fishes. Expand
Background colouration influences body colour segregation in mollies
TLDR
The results suggest that the presence of cryptic backgrounds alter shoalmate choices in fish that assort according to body colouration. Expand
Diet, familiarity and shoaling decisions in guppies
TLDR
The role of diet-based cues in the social decisions of domestic guppies, Poecilia reticulata, and potential explanations for the flake food-fed individuals' preference for unfamiliar fish are suggested. Expand

Phenotypic Variability within and between Fish Shoals
TLDR
Fish at the study site exhibited a significant association with conspecifics and with individuals of similar body size (within and across species); that is, shoals were assorted by species and by individual body size. Expand
Size‐assortativeness in multi‐species fish shoals
TLDR
Findings provide strong quantitative evidence for size-sorting in free-ranging fish Shoals and raise questions concerning the formation of multi-species fish shoals. Expand
Familiarity and shoal cohesion in fathead minnows (Pimephales promelas): implications for antipredator behaviour
TLDR
It is suggested that preferential shoaling with familiar conspecifics leads to an increase in cooperative antipredator behaviour and may thereby lower a minnow's risk of predation. Expand
Group Vigilance and Shoal Size in a Small Characin Fish
TLDR
The importance of the enhanced predator detection ability of fish shoals and the social transmission of alarms within them is discussed in relation to predator avoidance behaviour and other activities of fish in shoals. Expand
Antipredator benefits of schooling behaviour in a cyprinodontid fish, the banded killifish (Fundulus diaphanus)
TLDR
Individual risk of being attacked and killed by a fish predator declined with increasing killifish school size in a manner closely predicted by the dilution hypothesis, and straying from a school has an associated increased risk of mortality to predation, which selects for schooling behaviour. Expand
Species segregation during predator evasion in cyprinid fish shoals
TLDR
Behaviour which sorted fish into species at the onset of predator attack was revealed, and the value to the individual of segregative behaviour in response to predator threat is discussed. Expand
Size segregation and the effects of oddity on predation risk in minnow schools
TLDR
Schools of predominately large fish and predominately small fish were used to determine if odd-sized fish were eaten by large mouth bass, Micropterus salmoides, more often than other school members, and there was strong evidence for size segregation. Expand
Behaviour of Teleost Fishes
TLDR
This book discusses fish behaviour and the management of freshwater fisheries, behavioural ecology of cave-dwelling fishes, and the role of sensory modalities in fish behaviour. Expand
Assortative schooling in three-spined sticklebacks?
TLDR
It is suggested that, when schooling, it pays for small sticklebacks to group with small fish, as well as a large stickleback, which seems to do better in association with smaller fish than in schools of uniformly large fish. Expand
Schooling preferences for familiar fish in the guppy, Poecilia reticulata
TLDR
It is shown (in a laboratory study) that female guppies prefer to associate with familiar individuals, however, it is unable to detect any schooling preference for unfamiliar females from the same population. Expand
