1. Betta Fish
Scientific name: Betta splendens
Betta fish, also known as Siamese fighting fish, are a popular choice for beginners due to their stunning appearance and low-maintenance nature. They are small, brightly colored fish with flowing fins, which make them a captivating addition to any aquarium.
Bettas are labyrinth fish, possessing a unique organ that allows them to breathe air from the surface. This trait enables them to survive in low-oxygen environments, such as rice paddies and shallow ponds in their native Southeast Asia. As a result, betta fish are less demanding regarding water quality and oxygenation, making them ideal for novice fishkeepers.
Despite their beauty, betta fish are territorial, especially among males. They can become aggressive towards other bettas or fish with similar appearances. It’s best to house a single betta fish in a tank or choose peaceful tank mates that won’t provoke aggression. Suitable companions include small, fast-moving fish and bottom-dwellers that won’t intrude on the betta’s territory.
Betta fish are carnivorous and require a diet rich in protein. High-quality betta-specific pellets, as well as occasional treats of live or frozen brine shrimp, daphnia, or bloodworms, will ensure your betta receives the necessary nutrients.
When setting up an aquarium for a betta fish, provide ample hiding spots using decorations or live plants, like java fern or anubias. Bettas appreciate having places to hide and explore, which can help reduce stress and promote overall well-being. It’s also essential to maintain stable water conditions, as sudden changes in temperature or pH can cause stress and illness.
