Betta Fish
Betta splendens
The Betta fish (Siamese fighting fish) is one of the most popular freshwater aquarium fish in the world, known for its stunning flowing fins and vibrant colors. Males are territorial and should be kept alone or with carefully chosen tank mates. Despite their reputation as low-maintenance fish, bettas thrive best in heated, filtered tanks of at least 5 gallons.

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.
