I know nothing about it but how does the fish act? That would be my deciding factor. I grabbed this off google
Dwarf gourami disease (DGD). Sometimes caused by a bacteria, sometimes by a virus. Bacterial form may be treated at early stages with antibiotics; otherwise untreatable. Quarantine sick fish immediately as DGD is highly contagious. Provide optimal water conditions and hope for a natural recovery; otherwise destroy the fish painlessly. DGD is most easily avoided by not keeping dwarf gouramis, but instead opting for similar but resistant species such as Colisa labiosus and Colisa fasciata.
