Vegetable oil sources in diets for freshwater angelfish (Pterophyllum scalare, Cichlidae): growth and thermal tolerance [PDF]
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2011 The influence of fatty acid composition of the diets on the productive performance and on cold and heat tolerance of juvenile freshwater angelfish (Pterophyllum scalare), in three different phases, was studied.

When mesophotic meets shallow: First records of deep-associated reef fishes in a well-studied tropical bay under the influence of spring-summer upwelling. [PDF]
J Fish BiolAbstract We document the first records of reef fishes typically associated with mesophotic environments on shallow (<10 m) coral reefs inside a well‐studied tropical bay. The vermilion snapper Rhomboplites aurorubens and the pygmy angelfish Centropyge aurantonotus, usually restricted to deeper (>40 m) shelf habitats along the Brazilian coast, were ...

The role of body surface area in quantity discrimination in angelfish (Pterophyllum scalare). [PDF]
PLoS ONE, 2013 Although some fish species have been shown to be able to discriminate between two groups (shoals) of conspecifics differing in the number of members, most studies have not controlled for continuous variables that covary with number.

Resource partitioning among algal turf-feeding fishes on a tropical artificial shoreline. [PDF]
J Fish BiolAbstract Rapid coastal development has led to the proliferation of artificial structures along urban shorelines. Numerous studies have shown that patterns of fish diversity associated with these novel habitats are driven by physical habitat complexity; however, trophic‐mediated processes in shaping these patterns remain poorly understood.

Activity counts: the effect of swimming activity on quantity discrimination in fish
Frontiers in Psychology, 2012 Human infants and nonhuman animals can discriminate the larger of two sets of discrete items. This quantity discrimination may be based upon the number of items, or upon non-numerical variables of the sets that co-vary with number.

Exploring the Neural Substrates of Number Sense: A Perspective on Genetics, Behaviour and Neural Circuity. [PDF]
Eur J NeurosciNumerical cognition arises from conserved mechanisms linking genes, neural circuits and behaviour. Using zebrafish as a tractable model, behavioural assays, whole‐brain imaging and genetic analyses can be integrated to identify neural and molecular bases of quantity discrimination. This framework provides a platform for studying numerical cognition and
