Care notes
The largest gourami species. Highly intelligent — recognizes owners and can be hand-fed. Labyrinth fish. Juveniles are attractively striped; adults turn grey-gold. Incredibly long-lived (20+ years). Often kept in large ponds in Asia. Voracious appetite.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
