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.

Celestial pearl danios (also called galaxy rasboras) are tiny, jewel-like fish discovered in Myanmar in 2006. Their dark blue body is covered in iridescent pearl-white spots, with bright orange-red fins striped with black. Despite their exotic appearance, they are hardy and easy to care for — one of the hobby's best-kept secrets for nano tanks.
