![]() That said it is relatively boisterous and doesn’t make an ideal companion for very shy, slow-moving, or long-finned fishes such as many livebearers, cichlids, and anabantoids. Males will also show better colouration in the presence of conspecific rivals. It’s a gregarious species forming loose hierarchies, with rival males continually battling with each other for female attention and positioning within the group.Ī group of at least 8-10 specimens should be considered the minimum requirement since this increases the likelihood that the fish will be distracted by each other rather than their tankmates but will result in a more effective, natural-looking display. eques is notorious as an aggressive community inhabitant with a reputation for nipping the fins of tankmates although this behaviour tends to be most pronounced when insufficient numbers are purchased or space is limited. In aquaria it may survive on a diet of dried foods but like most fishes does best when offered a varied menu which in this case should also contain live and frozen chironomid larvae (bloodworm), mosquito larvae, Daphnia, Moina, etc. Likely to be omnivorous feeding on small invertebrates, crustacea, filamentous algae, fallen fruit and suchlike in nature. If you can get hold of wild stock slighty acidic to neutral water is advisable. ![]() PH: The farm-raised fish available in stores are fairly adaptable where water chemistry is concerned and should be happy within the range 5.0 – 7.5. The vast majority of fish available in the aquarium trade are bred on a commercial basis and are more adaptable than wild specimens. Leaves can be left in the tank to break down fully or removed and replaced every few weeks. ![]() These can provide a valuable secondary food source for fry, whilst the tannins and other chemicals released by the decaying leaves will aid in simulating natural conditions. The addition of dried leaf litter would further emphasise the biotope-style feel and with it the growth of beneficial microbe colonies as decomposition occurs. MaintenanceĬhoice of decor is not especially critical although it tends to show better colouration when maintained in a well-furnished set-up with live plants and a dark substrate.Ī natural-looking arrangement might consist of a soft, sandy substrate with wood roots and branches placed such a way that plenty of shady spots are formed. ![]() Maximum Standard LengthĪn aquarium with base dimensions of 80 ∗ 30 cm or equivalent should be the absolute minimum considered. Most typically inhabits still and sluggish tributaries and backwaters, including ponds and small lakes, where it forms aggregations around patches of marginal vegetation or submerged tree roots. It has been introduced in French Guiana via the aquarium trade. It’s possible that some or all of these names might be restored in the future since only H. Wild populations vary in colour pattern depending on origin, especially in the fins plus the size and shape of the humeral spot, and some populations have previously been described as species in their own right (see ‘Synonyms’), Type locality is ‘Villa Bella, Obidos’, referring to the town of that name on the Amazon river in Pará state, Brazil, located between Santarém and Oriximiná. eques has an enormous distribution throughout much of the Amazon drainage in Brazil, Peru and Bolivia plus the Río Paraguay in Brazil, Paraguay and Argentina, the upper part of which is connected to the Amazon via the rio Guaporé. Order: Characiformes Family: Characidae DistributionĪs currently understood (see below) H. Hyphessobrycon: from the Ancient Greek υπελάσσων (hyphesson), meaning ‘of lesser stature’, and used as a prefix in this case, plus the generic name Brycon.Įques: from the Latin eques, meaning ‘knight, horseman, rider’.
