Best Aquarium Fish for Beginners in India

Bettas are the most popular aquarium fish in India for good reason. They're stunning, full of personality, and can thrive in tanks as small as 5 litres. A single male betta in a planted nano tank is the perfect first setup. Care basics: Keep water temperature between 24–28°C. Feed 2–3 pellets twice daily. Change 25% of the water weekly. Never keep two males together — they will fight. At Aquatik, we breed and source premium betta varieties including Halfmoon Plakat (HMPK), Dumbo Ear, Crown Tail, and Nemo pattern fish. Popular picks for beginners include the Fancy HMPK (₹350), Crown Tail Red (₹400), and our budget-friendly Mix Color bettas (₹250). Every fish is quarantined and health-checked before dispatch.

Neon tetras are small, peaceful, and look incredible in groups of 6 or more. Their iridescent blue and red stripes catch the light beautifully in a planted tank. They're one of the most popular community fish worldwide. Care basics: They prefer soft, slightly acidic water (pH 6.0–7.0) and temperatures of 24–28°C. Feed quality flake food and supplement with frozen daphnia. A 40-litre tank is the minimum for a school of 6. They pair well with corydoras, guppies, and small plecos — making them ideal for community setups. For tetra food, we recommend SSF Twin Tails Tetra Food, available at Aquatik.

Guppies are one of the hardiest freshwater fish available. They come in dozens of colour varieties, breed easily, and tolerate a wide range of water conditions. Perfect for beginners who want a lively, colourful tank. Care basics: Temperature 22–28°C, pH 6.8–7.8. Feed flake food or micro pellets twice daily. They breed prolifically — if you don't want fry, keep only males. Guppies are extremely affordable and widely available across India, making them a great starting point for new hobbyists.

Corydoras are peaceful bottom-dwellers that help keep your substrate clean. They're social fish that should be kept in groups of at least 3. Their constant foraging behaviour is entertaining to watch. Care basics: Temperature 22–26°C, pH 6.0–7.5. They appreciate a sandy substrate (gravel can damage their barbels). Feed sinking pellets or wafers, supplemented with frozen bloodworms. We carry G1 Dry Bloodworm at Aquatik — an excellent supplement for bottom feeders and bettas alike. Corydoras make excellent tank mates for bettas, tetras, and guppies — they occupy the bottom level and don't compete for space.

Before buying fish, make sure you have the essentials: • Tank — minimum 10 litres for a betta, 40 litres for a community (we carry Cube Tanks from ₹300 and Mini Glass Betta Tanks from ₹250) • Filter — a gentle sponge filter works for most setups (Blue Pet Sponge Filters from ₹120) • Heater — keeps water stable at 24–28°C • Substrate — sand or fine gravel (AQUARICH Aquarium Soil at ₹250 is ideal for planted tanks) • Plants — Java Fern and Anubias are nearly indestructible (from ₹150) • Water conditioner — removes chlorine from tap water (Anti Chlorine available at ₹15) Cycle your tank for at least 7–10 days before adding fish. This builds up beneficial bacteria that break down fish waste. Skipping this step is the single biggest beginner mistake.
