Så här skriver Vierke ("Bettas, gouramis and other anabantoids", TFH 1988) om Trichogaster trichopterus (PALLAS, 1777):
...
Description (...) Ground color is blue-green to yellow-brown. The body is marked with a variable number of fine or coarse, but always irregular, wavy transverse bands. Round, orange or yellow spots mark the anal fin.
Distribution: In all Indo-China except Burma, in Indonesia east of Sumba, and in the northeast as far as the Philippines. In ponds, rice fields, lakes, drainage canals and rivers. Common everywhere. Prefers vegetated areas, even brackish water (...)
Breed strains: (...) Color changes are due in part to withdrawal of a pigment from the process (a ground color) as well as to irregular accumulation of pigment (Cosby gourami). Withdrawal of pigments is due to genetic changes (mutation) which can occur in the wild (possibly in blue gouramis) as well as in breeding tanks.
Blue gourami: No yellow or dark transverse bands, occasionally side spots are absent, too. Presumably a mutant which occurs in nature, even in a circumscribed area of Sumatra. Ladiges described the form in 1933 as Trichogaster trichopterus sumatranus.
Cosby gourami: Bred strain that exhibits a few thick transverse bands and spots in a blue ground. Apparently first produced by the American breeder Cosby.
Gould gourami: Bred strain without blue. Here the color hasactually been withdrawn (that is, does not participate), whereas it is involved in the blue gourami. Cross-breeding of these two forms produces the natural brownish form as well as the "pure" forms. All indications are against the often expressed opinion that this form has been bred from the blue gourami. All other color strains, too, are apparently from the wild form.
(...)
T.trichopterus captured in the wild exhibit various colorations depending upon "mood", which can change very quickly. Females, for example, are all dark with bright (!) body spots just before spawning, but after the spawning act, that is, not even a minute later, they are again light gray with black spots.
Jag tror att Vierke är pålitlig - han är den som namngivit min favoritfisk (Betta coccina)!
Att den blå varianten fått "sumatranus" som tredje namn betyder ju bara att den är en varietet/underart av T trichopterus, inte en ANNAN art.
