There are a few lists you need to check before you start your new aquarium hobby. You should start off with a few beginner fishes for which you need to check compatibility of the fishes, hardiness, maintenance (if they are easy to take care of), if they will fit in your tank and their personality that is, if they will be peaceful and get along with other fishes in your tank.

Now let us glance through the top 10 aquarium fishes for a beginner –

1. Livebearers

Guppy

Guppies – they come in almost every color you can imagine and look astounding. They’re very hardy, easy to take care of and can be kept in tanks as small as 20 to 40 litres. They’re a great community fish and you can keep them in groups of five or more. They breed very fast and hence it is wise to stock guppies of the same sex unless you want otherwise of course. Though they may survive higher or lower levels of pH, the recommended pH range for a guppy tank is between 6.8 and 7.6.

Swordtail

Swordtails – They are given this name due to their sword like tails.These fishes are great if you want to keep your plant leaves clean. They’ll also prevent proliferation of algae. They’re peaceful in nature and are great for a community tank. Minimum tank capacity for swordtails should be 100 as they grow large. Their water conditions range from moderately hard to hard although their water conditions are very low. They thrive better in communities, so it’s always better to keep more than one, preferably 5 or more. The optimal water temperature would be between 22-28 degrees Celsius, but they can also do well in cooler, or warmer tanks.

2. Betta 

Betta

This is one of the disputable fishes. The bettas are great to look at, their fin types are breathtaking and they can live in a community tank, but the conditions required might be a little confusing for a novice aquarist. It’s a good idea to keep a betta alone for a beginner, making sure his tank is at least 20 litres. They are easy to keep because they breathe from the surface. They may get territorial in a small tank, so a big tank is preferable if you’re planning on keeping them with other fishes. Just make sure to change the water on a regular basis and keep them at the right temperature (22-28 degree Celsius).

3. Danios

Zebra Danio

These fishes are robust, hardy, active and very tolerant to water conditions. Typically, they prefer to be in a group near the surface of the water. One of the best danios are Zebra Danios. They are appealing as they have black and white stripes down the length of their bodies just like Zebras do. They’re a perfect fit for those who don’t have much experience with setting up a tank. The zebra fishes love to swim, so keeping them in a larger tank will help them thrive. As the danios are schooling fish, we recommend to keep them in groups of at least 6. Other variants of Danios are the blue danio, danio kyathit, spotted danio, etc.

4. Gold Fish

Goldfish

This is a very notable fish with a gorgeous golden-orange color with fanned tails that everyone’s heard of or seen. They can be very easy to care for with a little research for beginners. Typically, you should give them 30 litres per fish and change 30% of water each week as they are nasty eaters. These fish prefer temperatures between 16-23 degrees Celsius. They can easily grow up to 4-6 in a year and upto 14 inches over the years.

5. Tetras

Black Neon Tetra

These fishes are popular choice among beginners due to their tiny size, stunning colors and vibrancy. We recommend them to keep them in groups of at least 10-12 as they are schooling fish. They grow only about an inch or so long, so any aquarium more than 40 litres or bigger is suitable for them. They are one of the easiest fishes to care for. They prefer tanks with a lot of live plants and a slow moving current. You can choose from neon tetra, cardinal tetra and many more.

6. Barb

Cherry barb

The Cherry Barb is still a favourite within the fishkeeping community, thanks to it’s bright, eye catching colours, and it’s entertainment value. There’s tiger barbs who are good for beginners but they are infamous for nipping fins of other fishes. They may take a while to adjust to their surroundings but once they get accustomed to their new surroundings, they’re fun to watch. They are best kept in schools, so anything above 6 is preferred. They are amiable, active and tolerant to changes in water parameters. Typically, the water temperature should be 22°C – 28°C. You can opt from a multitude of barb fishes such as the tinfoil barb, rosy barb etc.

Angelfish are generally equanimous, although they can become territorial if there is inadequate space for them to live happily. It is a regal fish but does not thrive in a small tank. You need a tank of at least 100 litres to keep an angelfish and it’s always better to use a tank that is 16 inches high or higher. Make sure you provide plants and other hiding places. They’re very hardy and easy to keep. They’re a cichlid so they might prey on very small fish but in general they make an apposite community fish. Typically, the water temperature should be 24 to 28 degrees Celsius.

Gourami

The gouramis are easy to take care of and can be kept in tanks of at least 100 litres and they require space at the top of the tank so they can breath air. They are undemanding and therefore are well suited to most community aquariums. They’re very hardy and can adapt to tough water parameters. Pearl gouramis would be an apt choice for beginners although they do not like thriving with fishes of aggressive demeanor. Moonlight gourami is also suitable for beginners.

They do well in a community tank with peaceful fish that are their size or larger. It is not recommended to keep them along with smaller fishes such as the neon tetra or zebra danios. They require a tank of size 75 litres at least and water temperature of 22.2 to 25° C and are surface dwellers although they love to swim around in the tank.
