No. You did not provide the serial number.
You mean a 1903 1903A3 or 1903A4? If you posted the serial I could tell you when it was made but that's about it for me.
The dorsdal fin of the female is rounded while the dorsal fin of the male is pointed.

If you email eaacorp@eaacorp.com with the serial number and model, they will tell you.
The "blue" Dwarf Gourami (Colisa lalia) is sexed the same way as all Dwarf gouramis. The male is brightly coloured and the female is much plainer.

Could be any year. Need the model name to tell.
Males have longer pointed dorsal fins. Females' dorsal fins are shorter and round.
