The best fish for a 5 gallon tank

A 5 gallon aquarium is one of the more popular sizes that you’ll see in homes. It might not be a huge amount of space, but there is enough room to stock some pretty fantastic varieties of fish. The most important thing here is to ensure that the fish you’re stocking will have enough room to be healthy and happy, otherwise they’ll be at risk of infection or even worse, death.

So when choosing what fish to stick in a 5 gallon fish tank, it’s crucial that you choose wisely. That’s why we wanted to outline the best fish to include in a tank this size, and how many fish you should have in a 5 gallon aquarium. Before we get started with the list of fish options, let’s figure out how many fish we can have in a tank of this size.

How many fish can you put in a 5 gallon tank?

There is no one size fits all answer here (please excuse the pun). When considering how many fish you’ll put in your aquarium, you’ll have to think about the size that your fish will be when it’s fully grown, and whether or not it will still be able to live comfortably in 5 gallons. You could always move the fish to a larger tank once they start growing in size, but a good general rule of thumb would be to consider what size the fish in your tank will be when they’re fully grown, and if they wouldn’t still fit comfortably in the tank then either get a larger aquarium or get some smaller fish!

 

What are the best fish for a 5 gallon tank?

Now we’re getting to the fun bit! Deciding on what fish to put in your tank is where the real enjoyment is, and although 5 gallons is pretty small you should be able to have some pretty tropical and interesting fish in your tank. For example, the most obvious type of fish to have in a tank of this size would be Betta fish, as they’re small and colorful. But there are some other types of fish you might like to consider for a tank of this size:

  • White Cloud Moutain Minnow
  • Honey Gourami
  • Clown Killifish
  • Least Killifish
  • Various Micro Rasboras
  • Dwarf Puffer

If you wanted to combine some of these fish alongside some plants or ornaments, then there are a few different variations you could go for. Killifish are probably best kept with other Killifish only, but Bettas are good with most types of fish, and all of the fish we listed above wouldn’t mind a few ferns or moss balls in the tank for some extra plant life.

So that is our guide for stocking fish in a 5 gallon tank. hopefully you have enough information to get started!
