Species Profiles
Discus
Symphysodon spp.
Discus are widely considered the king of freshwater aquarium fish. Their disk-shaped body, vivid colors, and graceful swimming make them the ultimate showpiece. However, they are among the most demanding freshwater fish to keep, requiring warm, soft, exceptionally clean water, frequent feedings, and a stress-free environment. Discus are not recommended for beginners.

Metynnis hypsauchen
Silver dollars are large, disc-shaped, peaceful schooling fish related to piranhas — but entirely herbivorous. Their shimmering silver body catches light beautifully in motion. They are excellent dither fish for large cichlid tanks because their calm, open-water swimming behavior helps reduce cichlid aggression. Warning: they will eat every live plant in your tank.
