Unfortunately, up to 22% of dwarf gouramis imported from India are sick with DGIV, the dwarf gourami iridovirus. Make sure to buy a DG that appears bold and confident, and in a tank that does not appear to have any sick fish. Can live up to 7 years under proper care.
Males are larger and more colorful than females. Males also have longer anal and dorsal fins.
