Best Fish to Buy as a Pet

So, you’ve decided that you fancy doing some fishkeeping, and you are eager to start filling your fish tank with fish. That’s great, but what is the best fish to buy as a pet?  Deciding on the best fish choice can be just one of the problems you encounter. In some cases, you might not be ready to take on the responsibility that comes with maintaining a saltwater tank or any of the high-maintenance fish that populate such aquariums.

A lot can happen when you start out fishkeeping, cloudy water might become an issue. You might even have to deal with dying fish in the event of a water change gone wrong.

Even if you opt to maintain a freshwater aquarium as a more manageable alternative, there is no doubt that you probably do not have the time, resources, patience, or expertise to look after fish which require a lot of attention. The good news is that there is plenty of freshwater fish which make easy starter options for new aquarium owners.

Best Fish to Buy

Goldfish Variants

This is as stereotypical as it gets when it comes to fish keeping options. That said, there is a very good reason for that. Goldfish are extremely easy to keep as pets, hence why they are the fish pet of choice for young children as their first gift.

They do not require too much food or attention, are not aggressive and come in a wide range of colours and varieties. As such, you can fill your tank with different goldfish variants and still enjoy a bright variety of colourful, different-looking fish without having to worry about mixing different types of fish and dealing with the “personality conflicts” that can come from that.

What’s more, goldfish don’t have special water needs, and anywhere between the low to mid-60s and 70s Fahrenheit tends to be fine temperature-wise.

There are literally hundreds of different goldfish species out available. Many fishkeepers are of the opinion that there are only 15 real species of goldfish, with the rest falling into one of those 15 categories.

The main goldfish species include –

  • Comet Goldfish
  • Shubunkin Goldfish
  • Wakin Goldfish
  • Japanese Ryukin Goldfish
  • Fancy Fantail Goldfish
  • Veiltail Goldfish
  • Telescope Goldfish
  • Black Moor Goldfish

Tetra Variants

These are relatively common in places that sell aquarium fish as well. They are slender, have streaked bodies, and move quickly throughout aquariums, all without requiring special food or conditions, and can be fine in temperatures ranging from the mid-60s to the low 80s.

Tetras tend to prefer to live in groups and can be reclusive if they’re the only one of their type in the tank. Still, they look their finest when travelling in packs anyway, and tend to be quite cheap, so getting a few shouldn’t be too much of a problem.

There are over ten variants of the Tetra fish, these include the following –

  • Neon tetra 
  • Lemon tetra
  • Buenos Aires tetra
  • Congo tetra
  • Glowlight tetra
  • Bloodfin tetra
  • Ember tetra
  • Bleeding heart tetra
  • Emperor tetra
  • Black skirt tetra
  • False penguin tetra
  • Diamond tetra

Black Mollies

One of the biggest conundrums facing first-time tank owners is the question of how to mix fish successfully. The last thing you want is to plop a few new fish in your tank only for them to start a vicious and ultimately tragic battle to the death.

Black mollies are the perfect starter fish for those new to fish keeping and wanting a tank with different types of fish. They are quite peaceful and can get along well with most freshwater fish.

Black Mollies are pretty small in size. The males often grow to a maximum of 3 inches, while the females only grow a few inches more. How long they live for completely depends on how well they are cared for, but ideally, Black Molly fish can live up to 5 years in a fish tank with no issues.

Black Mollies love planted aquariums, so the more oxygenating aquarium plants you have, the better. The plants will not only allow the adult fish to feel more comfortable, but they will also increase the survival rate of the fry.

Skirted Tetras

If you are looking for some fancy-looking long-tailed fish without having to deal with any of the high-maintenance prima donna types that commonly occupy that category, try a skirted tetra.

If you are planning on keeping a small school of Black Skirt Tetras, then at the very least you will need at least a 15-gallon fish tank no less than 20 inches long due to the fact that Skitered Tetras are very active swimmers.

Their long, flowing fins can appear quite lovely, and they themselves are very peaceful. As long as you don’t have tiny fish in your tank which might nibble at their long fins, they are a great starter choice. The great thing is taking care of skirted tetras is not a demanding task, making it the ideal choice for someone new to fishkeeping. It adapts well and it eats any kind of feed. The fish is good for community tanks at the condition that it won’t have long-finned tank mates.

As long as you are careful about choosing the right fish to start out with, keeping fish can be an incredibly fun and rewarding endeavour.
