Starting an aquarium can be a rewarding and fun experience! Choosing the right fish is key to your success and enjoyment. As a beginner, look for fish that are easy to care for, fit your tank size, and live peacefully with others.
Betta fish, also known as Siamese fighting fish, are a popular choice among newcomers. They have vibrant colors and are relatively easy to care for. However, they might not be the simplest option for absolute beginners.
To keep Betta fish healthy, you need at least a five-gallon tank with a heater and a filter. It’s essential to maintain the water temperature between 78 and 82 degrees Fahrenheit. Avoid overfeeding them, and provide betta-specific pellets for proper nutrition.
Key Takeaways:
- Choose fish that suit your tank size and how much maintenance you’re comfortable with.
- Betta fish are popular for their bright colors and manageable care needs.
- Use a properly sized tank with a heater and filter to create the best environment.
- Feed Betta fish a balanced diet of pellets made specifically for them, and don’t overfeed.
In this guide, we’ll explore some excellent fish options for beginners. You’ll learn about their care requirements and how they get along with other fish.
Upgrading Betta Fish Tanks
Betta fish need tanks that hold at least five gallons of water. A larger tank helps keep the temperature and water quality stable. Since Bettas prefer warm water, having a good heater with an adjustable thermostat is essential.
Most aquarium sets come with a heater preset to 76 degrees Fahrenheit, but this is too cool for Bettas. You should buy a separate heater to keep the water temperature between 78 and 82 degrees Fahrenheit.
Your tank should have little to no water flow to protect your Betta’s delicate fins. Avoid sharp or rough decorations that could injure your fish.
Creating the perfect home for your Betta fish is important for their health and happiness. Upgrading your tank can improve the look of your aquarium and provide a better environment for your fish.
Here are some key tips to help your Betta fish thrive:
Choose a Tank of at Least Five Gallons
Betta fish are not very active swimmers and don’t need a lot of space.
However, a tank between 5 and 10 gallons offers better water circulation and dilutes toxins. This leads to cleaner water and reduces how often you need to change it.
Use a Heater to Keep the Right Temperature
Betta fish come from warm, tropical waters. Buy a reliable aquarium heater and set it to keep the water between 78 and 82 degrees Fahrenheit (25-28 degrees Celsius). This matches their natural habitat and supports their health.
Install a Thermometer to Monitor Temperature
Place a thermometer in the tank to make sure the water stays at the right temperature. This allows you to adjust the heater as needed. You might also get a high-quality heater with a built-in thermometer, but having a separate one at first is helpful.
Create a Gentle Water Flow
Bettas have delicate fins that can tear in strong currents. Use a filter with adjustable flow settings and set it to the lowest level, or add a baffle to reduce the flow. Gentle water movement reduces stress and protects your Betta’s fins.
Avoid Sharp or Rough Decorations
Choose tank decorations that are smooth and free of sharp edges. Bettas can hurt themselves on rough surfaces, leading to torn fins or other injuries.
Soft live plants, smooth rocks, and ceramic decorations are good options.

Keeping Common Goldfish as Beginner Pets
Common goldfish are a popular option for new fish owners. These hardy fish can grow quite large, but they are relatively easy to care for, making them suitable for beginners.
Goldfish can reach lengths of 12 to 14 inches, so providing enough space is important. Each goldfish needs at least a 30-gallon tank to ensure they have room to swim and grow. A good filtration system is essential to keep the water clean and maintain proper oxygen levels for these active fish.
One advantage of keeping common goldfish is their resilience. They can tolerate a wide range of water conditions, which is helpful for beginners still learning to maintain stable aquarium environments.
However, regular water changes are necessary to prevent ammonia buildup and keep the fish healthy. In some cases, changing 50% of the water every week is necessary, especially if you have fully grown goldfish.
“Common goldfish are an excellent choice for those starting out with fish keeping. Their bright colors and lively personalities will quickly make them the highlight of your aquarium.”
Feeding Common Goldfish
Providing proper nutrition is important for the health and growth of goldfish.
They do well on a varied diet that includes spirulina algae, vegetables, and other foods rich in carbohydrates. High-quality goldfish pellets or flakes should be the main part of their diet, with occasional treats like frozen or live foods.
Feed goldfish small portions several times a day. This helps prevent overeating and reduces the risk of water pollution from uneaten food. Watch your goldfish’s behavior and adjust feeding amounts as needed to prevent obesity and related health problems.
“Feeding your goldfish correctly is key to their overall health and long life. By offering a balanced diet and keeping an eye on their eating habits, you can ensure your aquatic friends stay healthy and happy.”
Decorating the Goldfish Tank
Creating an appealing and stimulating environment is important for goldfish well-being. When choosing decorations, consider their large size and potential for accidental injury. Avoid sharp or rough decorations that could harm their fins. Choose soft, smooth items instead.
Goldfish need plenty of swimming space, so don’t overcrowd the tank with too many decorations or plants. Include a few carefully chosen items that provide hiding spots or areas to explore.
Live plants like java fern or hornwort can improve water quality and offer natural shelter.
Goldfish Care Tips
- Provide a spacious tank of at least 30 gallons per fish.
- Use a reliable filtration system.
- Perform regular water changes to keep the water clean.
- Feed a balanced diet of commercial goldfish pellets, vegetables, and spirulina algae.
- Avoid sharp or rough tank decorations.
“With proper care and attention, common goldfish can thrive and bring joy to fish keepers of all experience levels. Their captivating beauty and playful antics make them a wonderful choice for anyone looking to create a vibrant and lively aquarium.”

To create a visually stunning display, keep tetras in schools of six or more. Some people prefer groups of 20. In larger numbers, tetras feel secure and show their natural behavior, creating a captivating sight in your tank.
Tetras get along well with other friendly fish like rasboras and corydoras. This allows you to build a harmonious and diverse underwater community that will delight you and your guests.

Corydoras – Peaceful Bottom Dwellers
If you want to add activity and diversity to your aquarium, consider Corydoras, also known as cory catfish. These peaceful, bottom-dwelling fish are perfect for beginner aquarists. They bring unique charm to your tank and help keep the substrate clean by scavenging for leftover food and debris.
Corydoras come in various species, each with distinctive features. Popular ones include bronze corydoras, albino corydoras, panda corydoras, and emerald green corydoras. Their fascinating patterns and colors make them a visually appealing addition to your underwater landscape.
These active and playful fish constantly search for food on the tank floor. They are known for their adorable habit of jostling each other, which adds amusement to your aquarium.
To ensure your corydoras thrive, keep them in groups of at least three to six of the same species. This allows them to exhibit natural behavior and promotes healthy interaction within the group.
When keeping corydoras, make sure your tank has suitable substrate like fine sand or smooth gravel to prevent damage to their delicate barbels. Providing hiding spots with caves or driftwood will also make them feel more secure.
Common Corydoras Species
| Species | Size | Preferred Water Parameters |
|---|---|---|
| Bronze Corydoras (Corydoras aeneus) | 2.5–3 inches | Temperature: 72–80°F pH: 6.0–8.0 Hardness: 2–25 dKH |
| Albino Corydoras (Corydoras paleatus) | 2–2.5 inches | Temperature: 72–80°F pH: 6.0–8.0 Hardness: 2–25 dKH |

Provide a balanced diet for your corydoras, including high-quality sinking pellets or wafers designed for bottom-dwelling fish. Supplement their diet with frozen or live food like bloodworms or brine shrimp to offer them varied and nutritious meals.
With their peaceful nature and fascinating behavior, corydoras make an excellent addition to any community aquarium.
They are especially suited for beginners and their compatibility with a wide range of fish species allows you to create a harmonious and captivating underwater world.
Platies – Robust Livebearers
Platies are a top choice for beginner fish keepers because they are hardy and brightly colored. These small fish adapt well to different water conditions, making them ideal for new aquariums.
They come in many colors, including bright oranges, reds, blues, and yellows. Their bold appearance adds a splash of color to any tank.
One key advantage of platies is their ability to tolerate a pH of 7.0 and higher. This flexibility allows them to thrive in various water environments, which is helpful for beginners still learning about water parameters.
Whether your water is hard or soft, platies can adapt and thrive.
Platies have hearty appetites and readily eat a variety of foods. They accept flakes, pellets, freeze-dried and frozen foods, and fresh vegetables. Feeding them a varied diet ensures they get all the nutrients they need for good health and vibrant colors.
Another reason platies are great for beginners is that they are easy to care for. They are low-maintenance fish that require minimal intervention.
Regular water changes and basic tank maintenance—like checking water parameters and cleaning the tank—are usually enough to keep them healthy.
Platies are social fish that enjoy the company of their own kind. Keep them in groups of at least three to six to encourage natural behavior and interaction.
They also coexist peacefully with other friendly fish like tetras, rasboras, and corydoras, creating a harmonious and vibrant aquarium environment.
Betta Fish – Beautiful and Low-Maintenance
Betta fish, also known as Siamese fighting fish, are popular among beginners because of their vibrant colors and simple care needs. They come in shades of red, green, purple, and blue, making them a beautiful addition to any aquarium.
Tank Requirements
You can keep a betta alone in a 5-gallon tank or with compatible species in a larger tank. Male bettas are territorial and can be aggressive toward other male bettas. It’s important to avoid keeping multiple male bettas together.
Choosing Tank Mates
For a beginner-friendly betta tank, choose peaceful fish with similar water requirements. Tetras and corydoras are good companions for bettas. Always research and make sure new fish are compatible before adding them to the tank.
Feeding Betta Fish
Betta fish need a balanced diet to stay healthy. Feed them betta-specific pellets, frozen bloodworms, and other small floating foods. Avoid overfeeding to maintain good water quality and keep your fish healthy.
Barbs – Active Fish for Community Tanks
Barbs are lively and energetic fish, making them a popular choice for community aquariums. Their vibrant colors and playful behavior add excitement to any tank. Popular barb species for beginners include:
- Tiger Barb
- Odessa Barb
- Cherry Barb
These barbs grow to about three to four inches in length, which suits medium-sized tanks. To keep them happy and reduce fin nipping, keep at least six barbs of the same species together. This encourages a more peaceful environment.
Barbs can live well with other community fish like rasboras, tetras, and corydoras. However, they might show aggression toward long-finned fish like angelfish and bettas.
Always research the temperament and compatibility of fish species before adding them to your tank.
If you want active, colorful, and beginner-friendly fish, barbs are an excellent choice. Their energetic nature and striking appearance make them a captivating addition to your community tank.
