Top 5 Fish and Plants for a New Aquarium Keeper
At first glance, an aquarium may seem like nothing more than a glass box filled with water. You might see fish and maybe some plants, but most people don’t realize the complex chemistry happening inside. Ions fluctuate constantly, temperatures shift gradually, and beneficial microbes sustain life. To start your aquarium off right, we’ve compiled a list of hardy, colorful fish and resilient, easy-to-grow plants. These choices will help you build a thriving ecosystem in your home.
Top 5 Fish for Beginners
1. Molly
Mollies are popular livebearers ranging from 3 to 5 inches depending on sex and breed. Sailfin mollies grow larger, and males tend to be smaller than females. A 29-gallon tank is ideal, with a ratio of one male to two or three females to minimize aggression. Mollies tolerate a wide range of water conditions and accept most foods. While generally peaceful, their energetic nature can stress shy or skittish tankmates. Uniquely, mollies are euryhaline, capable of living in both freshwater and marine environments.
2. Harlequin Rasbora
These small schooling fish have a muted red-brown color and grow up to 2 inches long. Keep them in groups of six or more in at least a 20-gallon long tank to see their best behavior. They’re peaceful, adaptable to various tank setups, and eat most foods offered. Avoid housing them with aggressive or much larger fish, as their calm nature makes them easy targets.
3. Pearl Danio
Pearl Danios are colorful and very active, growing just over 2 inches. They thrive in larger tanks with ample swimming space—ideally a 33-gallon long or 40-gallon breeder. Like other Danios, they’re schooling fish, so keep them in groups of six or more. Pearl Danios are hardy, undemanding about decor, and accept a wide variety of foods. However, their fast movements can stress slower surface-dwellers like gouramis or bettas.
4. White Cloud Mountain Minnow
White Clouds are small (up to 1.5 inches) and well-suited for tanks as small as 10 gallons. They’re peaceful, hardy, and thrive in schools of six or more. This species comes in both silver and gold color variants, which can be mixed. They tolerate a wide range of conditions and aren’t picky eaters. For best coloration and health, provide a mix of prepared and frozen foods. Avoid housing them with large or aggressive fish.
5. Zebra Danio
Zebra Danios are among the most beginner-friendly fish due to their hardiness and low cost. They reach 1.5 to 2 inches and should be kept in groups of six or more in at least a 20-gallon long tank. Extremely active, they benefit from ample space. They eat most foods and tolerate various water parameters. Avoid large or aggressive tankmates. They also breed easily and may even spawn in your tank unintentionally.
Top 5 Plants for Beginners
1. Samolus parviflorus ‘Red’ (Lysimachia parvifolia)
This lesser-known plant has gained popularity for its color versatility and compact size. It does not require CO2 and grows slowly in low light but faster with CO2. In low light, it stays green; in medium light, it appears yellow; and in high light, it turns red. Ideal for the foreground or midground.
2. Anubias ‘Pinto’
A variegated version of Anubias, this plant features leaves with striking green and white patterns. It thrives in low to high light and doesn’t need CO2. Growth is slow due to reduced chlorophyll in the white portions. Attach it to rocks or driftwood, as it’s a rhizome plant and should not be buried.
3. Giant Hygrophila (Hygrophila corymbosa)
Also called Temple Plant, this fast-growing background plant doesn’t require CO2, though CO2 will double leaf size. It grows tall and produces side shoots quickly, filling tanks easily. Most variants stay green, but the ‘stricta’ variant can turn reddish-brown under high light.
4. Crystalwort (Riccia fluitans)
This liverwort is similar to mosses in growth and care. It thrives in low to high light and grows quickly. Attach it to decorations or allow it to float. Always bright green, it’s a resilient and flexible plant ideal for beginners.
5. Rotala rotundifolia
A versatile stem plant that grows in a variety of conditions. It has moderate to fast growth and is suitable for midground or background placement. Variants include green, red (H’ra or Colorata), and even orange (Orange Juice). Resilient and attractive, it’s a staple in many beginner tanks.
These fish and plants provide a solid foundation for new aquarists. By choosing hardy species and easy-care plants, you can build a thriving ecosystem that’s as enjoyable to maintain as it is to observe.
