Care notes
Famous for swimming upside down — an adaptation to feed on the underside of leaves and logs. More active at night. Peaceful community fish. Keep in groups of 3+ for best behavior.
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.
