“…La alimentación y nutrición son esenciales para la salud y supervivencia de los peces ornamentales. Diferentes autores han demostrado que la cantidad requerida de alimento diario para mantener el peso corporal varía según la especie, reportando el consumo de 2.4% del peso corporal/día para Danio rerio, 1.9% para Paracheidon innesi, menor de 1.5% para Trichopodus microlepsis y 1% para Pelvicachromis pulcher [16].…”

La comercialización de peces ornamentales se ha convertido en una actividad económica de gran importancia para la acuicultura a nivel mundial, destacando la participación de Singapur, España, Japón, Malasia e Indonesia en la lista de principales productores a nivel mundial. Este documento busca recopilar y destacar la importancia de algunos estudios que describen los requerimientos nutricionales en especies ornamentales con potencial productivo y sobresale una problemática local, en donde se toman dietas formuladas con requerimientos nutricionales de especies de consumo humano, para alimentación de especies con potencial ornamental. La extrapolación de los requerimientos nutricionales de especies de consumo para la formulación de dietas en especies con potencial ornamental puede comprometer el crecimiento del animal o afectar directamente la calidad del agua por excesos de nutrientes.

“…Fish are poikilothermic aquatic animals who inhabit a complex three-dimensional environment which directly influences their welfare [ 62 ]. Water conditions outside of the species-specific optimal range can have long-lasting effects on fish physiology and welfare [ 29 , 34 , 63 , 64 ] as water quality is critical for ensuring the health and longevity of the fish [ 8 ]. Therefore, our first task was to define the optimal water quality and maintenance parameters for paradise fish [ 29 , 62 ].…”

“…Besides being “good practice” that helps experiments, optimal husbandry should also take into account that new research guidelines aim to cause minimal discomfort to the studied animals [ 27 , 28 ]. The complexity of the paradise fish behavioral repertoire is similar to that of some birds or mammals, suggesting that fish are most likely sentient beings [ 27 , 28 , 29 , 30 , 31 , 32 ], which is also supported by the presence of analogous brain structures and functions to other vertebrates [ 33 , 34 ]. Multiple lines of evidence also support that fish (in general) possess more complex cognitive abilities than often given credit for [ 30 ].…”

Thanks to its small size, external fertilization and fecundity, over the past four decades, zebrafish (Danio rerio) has become the dominant fish model species in biological and biomedical research. Multiple lines of evidence, however, suggest that the reliance on only a handful of genetic model organisms is problematic, as their unique evolutionary histories makes them less than ideal to study biological questions unrelated to their historically contingent adaptations. Therefore, a need has emerged to develop novel model species, better suited for studying particular problems. The paradise fish (Macropodus opercularis) has a much more complex behavioral repertoire than zebrafish and has been a favored model animal in ethological research during the last decades of the previous century. We believe that with currently available, easily adaptable genetic toolkits, this species could be easily developed into a popular model of behavioral genetics. Despite its earlier popularity, however, the description of a detailed housing and husbandry protocol for this species is still missing from scientific literature. We present here a detailed description of how to raise and breed paradise fish successfully under laboratory conditions, and also discuss some of the challenges we faced while creating a stable breeding population for this species in our facility.

“…Many of the species living in human custody show elaborate social behaviours, like the shoal living zebrafish ( Danio rerio ) and three‐spined stickleback, many social cichlids or the highly aggressive Siamese fighting fish. This includes highly derived communication during aggressive encounters (Balzarini et al, ; Pleeging & Moons, ; Rick & Bakker, ). Understanding aggressive communication is therefore a crucial step to minimize agonistic interactions in such species.…”

1. Aggressive interactions are ubiquitous among animals. They are either directed towards heterospecifics, like predators or competitors, or conspecifics. During intraspecific encounters, aggression often serves to establish hierarchies within the social group. Thus, in order to understand the mechanisms mediating social organization, it is important to comprehend the escalation and avoidance of aggressive behaviour.2. Overt aggressive interactions are costly not only in terms of increased risk of injury or death, but also due to opportunity costs and energy expenditure. In order to reduce these costs, animals are expected to communicate their strength and aggressive motivation prior to fights. For this purpose, they use different means of communication in various sensory modalities, that is visual, acoustic, chemical, mechanosensory and electric cues. These different modalities can convey different or similar information, underlining the importance of understanding the multimodal communication of aggression.3. Thus far, most studies on signalling during aggressive encounters have focussed on visual or acoustic cues, most likely as these are the two modalities predominantly used by humans. However, depending on the species' ecology, visual or acoustic cues might play a minor role for many species. Especially in aquatic systems, visual communication is often hampered due to high levels of turbidity or limited light conditions. Here, alternative modalities such as chemical, mechanical or electrical cues are expected to play a prominent role. 4. In this review, I provide an overview of different modalities used during aggressive communication in aquatic organisms. I highlight the importance of studying the role of multimodal communication during aggressive encounters in general and discuss the importance of understanding aquatic communication in the light of conservation and animal welfare issues.

Animals communicate when coordinating cooperative behaviours, choosing a mating partner, raising their offspring or avoiding predators. Understanding animal communication is thus crucial to understand animal behaviour in general. Consequently, animal communication has become a central topic in behavioural research within the last decades, witnessed by the publication of considerable numbers of scientific studies and textbooks focussing on different facets of this fascinating topic, ranging from the physiological foundations to the evolutionary consequences of animal communication (e.g., Bradbury & Vehrencamp, 1998; Maynard Smith & Harper, 2003; Stevens, 2013). Given the ubiquitous importance of animal communication in multifarious fields of research, it is not astonishing that there exists a huge variety of different definitions of terms.
