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.

Thorichthys meeki
Firemouth cichlids are one of the most beginner-friendly Central American cichlids. Named for their striking red/orange coloration on the throat and belly, they are less aggressive than most cichlids of their size. When threatened, they flare their gill covers to display their bright red throat — a bluffing display that is far more bark than bite.
