If you’re still wondering what you should do?

Good news!

Below we will answer all these questions and even show you some other tiny things that you can fit comfortably in your 10-gallon tank.

Let’s begin.

Question #1:
How many fish can be in a 10-gallon tank?

Ah, the classic question!

And it deserves a classic answer: It depends!

Seriously though, try to aim for one small fish per gallon of water and by “small” fish I mean like a Neon Tetra sized fish.

Basically, it equates to approximately 1 inch of fish per gallon.

But it’s not always that easy, you can see my thoughts on that here to see what I really think.

That said, you should be able to fit about 5-10 small fish in your tank at first and as the tank matures and you get better at fish keeping. You can maybe keep 10-20 if you don’t mind some work.

Question #2
What types of fish can live in a 10-gallon tank?

There are so many fish you can keep in your tank it just really depends on your skill.

If you’re here I’m going to assume you’re somewhat new to fishkeeping and looking for some guidance.

So, a few reasonable choices for a 10-gallon aquarium would be:

Some great Tetras would be the Neon, Cardinal or the Glowlight.

Dwarf and Panda Corydoras would be a fun addition.

Sparkling Gourami.
These guys are small but beautiful.

Try not to get males and females, these guys will breed like crazy and quickly overtake your 10 gallons.

Seriously only one of these guys, its not fight club.

But as you’ll see below we throw a few unexpected fish into the mix, so keep reading.

Stocking a 10-Gallon Tank Top Fish

As I mentioned above small tanks are easily contaminated due to the small amount of water, so you need to pay close attention to the bioload and water parameters.

If none of the above fish species are what you’re looking for in terms of fish, then you should explore a larger tank.

A larger tank is not only easier to maintain but will provide you with the opportunity to keep a wider selection of fish.

Question #4:
10-gallon fish tank stocking ideas?

This is a great video from Aquarium Co-Op where they show you some great ideas for your tank and walk you through the process of selecting some awesome fish to create something absolutely stunning.

In the video, they explain how to select a centerpiece fish along with some schooling fish, bottom dwellers as well as some plants.

Question #5:
How many Betta fish can I put in a 10-gallon tank?

Unless you plan on splitting your tank with a divider like this one you should never keep more than one male Betta in one tank.

Question #6:
How many female Bettas can you put in a 10-gallon tank?

However, female Bettas are not nearly as aggressive as males and you can have what’s called a sorority tank.

The trick with keeping the drama to a minimum between the sisters is to keep odd numbers when stocking your tank.

Try to keep 3 or 5 betta fish in a 10-gallon tank.

Question #7:
How many male Guppies can I put in a 10-gallon tank?

Guppies are great little fish especially the fancy varieties available in so many different colors and combos.

You could fit about 4-6 guppies in a 10-gallon tank. But like I said earlier keep with one sex to avoid any unwanted babies.

Question #8:
How many Goldfish can fit in a 10-gallon tank?

So, in this case, a lot of sites like this one will say you can keep 2-4 “Small” goldfish in a 10-gallon tank.

I completely disagree with this!

Although the rule of thumb may be 1 inch of fish per gallon. Goldfish grow far too large and are very dirty fish that will pollute a 10-gallon tank very quickly.

Question #9:
The Best 10-gallon tank fish combos

In most cases ten gallons isn’t suitable for a large community tank but here are a few options you can try:


  • 3 Tea Cup Platies
  • 5 Neon Tetras
  • 1 Nerite Snail


  • 1 Dwarf Gouramis
  • 4 Rasbora
  • 4 Corydoras


  • 4 Cardinal Tetras
  • 3 Corydoras

At the end of the day, a 10-gallon tank is not for beginners so make sure you know what you are getting into.

It’s important to understand the nitrogen cycle and how to maintain healthy water conditions for your fish.
