Species Profiles
Congo Tetra
Phenacogrammus interruptus
Congo tetras are the showstoppers of the tetra family. Males develop spectacular flowing fins with an iridescent rainbow sheen that shifts from blue to gold to green under aquarium lighting. They are larger than most tetras (up to 3.5 inches) and need a spacious, well-planted tank to display their full beauty. Peaceful but shy — they thrive with calm tank mates.

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.
