Honey Gourami colors:
Current latin name "Trichogaster chuna", old latin names may include "Colisa chuna" amongst others.
"Wild / Natural / Standard" color honey gourami:
Male in neutral mood. This is how it might look in a fishstore
Male in breeding dress.
Female
"Sunset" color honey gourami:
Sometimes also listed as "Red Sunset", "Gold honey gourami", etc because the fish stores love fancy names and some of them like to add a few more names for fun and to make it extra confusing.
Male
Female and male.
Males of this variety do not have as large changes in color when breeding as the wild color, but they get somewhat of a black line at the bottom.
"Red" color honey gourami:
Sometimes listed as "Red Robin honey gourami".
Sold under same latin name as the other honeys although likely to be a hybrid due to body differences.
I was unable to find a clear picture showing a female of this variety, I assume females may be less easy to tell apart than in other forms.
DIFFERENT SPECIES:
Red Dwarf Gourami
Current latin name "Trichogaster lalius", but more commonly sold under the latin name "Trichogaster lalia" or "Colisa lalia".
Male red dwarf gourami. Females will be silver color without much if any red.
If you search for red gourami on google this will come up. This is a different species.
This species has several bred color varieties and even just this red form can be sold as Red, Flame, Red Flame, Blood Red, basically any name you can think of.
This species has a different temperament as well as being more susceptible to illness.
I hope this helps, I tried really hard to make it clear but all the fancy names dont help.
If this made it worse I will stop trying and leave well enough alone
