Species Profiles
Bristlenose Pleco
Ancistrus spp.
The Bristlenose Pleco is the most popular pleco species for home aquariums, and for good reason — they stay small (4–5 inches vs 12–24 inches for common plecos), are excellent algae eaters, and are hardy and easy to care for. Males develop distinctive bristle-like growths on their nose, which is how they get their name.

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.
