Finally, they are easy to keep because they eat both plants and flesh so you are under no restrictions when it comes to providing them food. Being so tiny, you can actually keep about 6 of these nano fish in a 10-gallon aquarium. I’ve personally seen them swim together with White Cloud Mountain Minnows in the same aquarium but the Zebra Danios will let any other schooling fish join them.

They are a good match for other peaceful types of fish that enjoy lingering in different parts of the tank. True to their name, the neon rainbow fish dazzles with its iridescent scales, particularly when they swim against well-planted tanks. Because of their timid nature, we recommend keeping these fish in groups of at least 6 individuals. These cute Catfish only reach around 2.5 inches in length and prefer to be kept in groups. They will be happy with a partner but will become most active in larger groups. These tiny shoaling fish are one of the most recognizable in the aquatics trade.

  • These are the least expensive option and work very well for smaller tanks.
  • When kept in a community aquarium, they are well-behaved and will leave other fish and corals alone.
  • You need to think about where you’ll place it and what type will suit your needs.
  • By choosing the right equipment, plants, and decor and setting up effective filtration, you'll create an aquatic ecosystem that largely takes care of itself.

While they prefer to be kept with six to eight of their own kind, they don't need to be housed in a species-specific tank thanks to their gentle nature. A hardy species of fish native to China, the white cloud mountain minnow is a graceful and peaceful community fish that likes to be paired with at least five others of its species. Measuring 1.5 inches in length and living for around three to five years, they're a good fish for beginners and are easy to breed. White cloud mountain minnows do not like heat and need to be kept in water with a temperature below 72°F.

Even if you’ve chosen hardy fish as your starter fish, you’re still going to expose them to toxins, which will eventually reflect in their health. It goes without saying that adding small fish to a tank with larger fish is also a no-no, since the bigger fish will mistake the smaller ones for food. So, you’ll need to perform water changes and clean the tank regularly to keep nitrate levels under control. If you add fish to a tank that hasn’t gone to a cycling process, ammonia levels will spike because of the waste fish generate.

Stable water conditions and a balanced diet of flake food, supplemented with occasional live or frozen treats, will support their health and vibrant colors. Beginners will appreciate their easygoing nature and the lively dynamics they introduce to the tank. While they can adapt to a variety of water conditions, maintaining clean and well-oxygenated water will ensure their health and happiness. Their diet should include sinking pellets and occasional live or frozen foods to mimic their natural foraging habits.

They often have tails dressed with feathers, animal hair or rubber skirting to attract bass, trout, pike and other species in shallow streams, deeper rivers and lakes.
