everything about the snakeskin gourami
how to recognize it
Deep-bodied, laterally compressed gourami with oblique dark bands along the body, which are not always well marked. It has an irregular black band running from the eye to the base of the caudal fin. The dorsal fin has short spines and long soft rays, the caudal fin is slightly notched, and the first soft ray of the pelvic fins forms a filament that reaches the base of the tail. To tell it apart from the giant gourami, look at the oblique bands and the black band from the eye to the tail, which are absent in adult giant gouramis.
Also called: gurami-pele-de-cobra, gurami piel de serpiente, snakeskin gourami

where found
open on the large mapWhere to look: Shallow, still waters with dense vegetation, and flooded forests.
Native to Asia, in the Mekong and Chao Phraya basins, and introduced to Colombia. Not recorded in Brazil.
rules for the snakeskin gourami
Rules change; before keeping or transporting fish, check with the state environmental agency.
We found no species-specific rule beyond the region's general rules.

how we calculate
Length-weight relationship W = a·Lb (a = 0.01318, b = 3.06; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.
more about the snakeskin gourami
Gourami of the family Osphronemidae, freshwater, reaching 25 cm and weighing up to 500 g. It lives in shallow, still waters with dense vegetation, in the flooded plains of the Mekong and Chao Phraya rivers, and returns to the rivers when the waters fall. It eats mostly aquatic plants. It breathes air directly and also absorbs oxygen from the water through its gills. Its flesh is of good quality, and it is farmed for food and for export as an aquarium fish. It has been introduced to Colombia and, in at least one country, has had an ecological impact.
Family: Osphronemidae · omnivore
fun facts
- The male builds a bubble nest at the surface and guards the eggs until they hatch; both parents care for the young.
in the kitchen
The flesh is of good quality: it can be grilled or used in soups, and the fish is sold fresh.

Essential profile: size, length-weight, depth, countries and conservation come from FishBase and the cited regulations, and the texts were written from those sources. Season, time of day, sensitivities, technique and baits and lures are not included yet, because we did not find a good source for this species.

how we calculatewhere each number comes from
The weather comes from three independent global models, cross-checked hour by hour: when they agree, confidence goes up; when they diverge, the band between them shows on the chart. Beyond 16 days, we use the GEFS ensemble of 31 simulations: if 20 of the 31 predict rain, the chance of rain is 65%. Sun and moon are calculated astronomically, with no uncertainty.
The index adds up, weighted for each species: time of day (species curve anchored to real sunrise and sunset), moon (transits, rise and set, phase), pressure (3 h trend and 24 h swing), water temperature (in rivers, estimated from air temperature; at sea, estimated by an ocean model), wind, rain, clouds, tide and the month in the species' cycle.

how accurate the forecast is
Accuracy measured in the reference project (4 regions, 93 days, forecast vs. observed): maximum temperature is off by 0.6 °C on average the next day and 1.7 °C at 7 days; rain of 5 mm or more is detected 76% of the time the next day and 57% at 7 days. Detection isn't everything: the false alarm rate isn't published here yet, and 93 days in 4 regions is still a small sample. We now also measure every day, at the app's destinations:
