GloFish are brightly colored fish that are perfect for anyone new to the fish keeping hobby. At first, GloFish were originally only available in one species, the Zebra Danio. Now they come in four different species that range in size from 2 to 6 inches. That makes answering the question of how many GloFish in a 10 gallon tank a little bit trickier. In the following article we will go over each GloFish species, and then we will give our recommendations on how many of each GloFish can be added to a ten-gallon aquarium.
How many GloFish in a 10 Gallon Tank

How many GloFish Danios in a 10 Gallon Tank
The GloFish Danio (Order GloFish online at Petco.com) is a small schooling fish that is the perfect size for a 10-gallon tank. The GloFish Danio will reach a maximum adult size of about 2.5 inches. That means you can comfortably fit up to 5 GloFish Danios in a 10-gallon tank.
GloFish Danios are a very social fish that need to be kept in small schools, or with other non-aggressive fish. They also prefer to live in a tank with wide open swimming spaces, since they love to dart around and chase their tank mates.
Danios, in general, are very easy to care for and can tolerate a wide range of conditions. They live in water that ranges from 64-75 degrees Fahrenheit, so they can be kept in a tank without a heater. And they are very tolerant of poor water conditions so they are perfect for beginners or anyone cycling a new tank.
How many GloFish Tetras in a 10 Gallon Tank
The GloFish Tetra (Order GloFish online at Amazon.com) is a very peaceful, schooling fish that comes in a wide range of eye-catching colors. GloFish Tetras will remain small throughout their life since they only reach a maximum adult size of 2.5 inches. That means you will easily be able to keep up to 5 GloFish Tetras in a 10-gallon tank.
Keeping GloFish Tetras is very easy since they get along with all kinds of non-aggressive fish. That makes them a great addition to a community tank, or you can keep them in a species specific tank if you like. And unlike GloFish Danios they tend to be more relaxed and laid back, so they don’t need as much wide open swimming space.
Tetras are a very hardy tropical fish that are perfect for someone who is just starting out in the fish keeping hobby. They are not as cold tolerant as GloFish Danios though since they prefer temperatures that range from 72-82 degrees Fahrenheit. That means you will need to keep them in a tank with a heater. They can also be shy, so you should give them lots of decorations to hide in so they have a place to feel safe.
How many GloFish Tiger Barbs in a 10 Gallon Tank
GloFish Tiger Barbs (Order GloFish online at Amazon.com) are a semi-aggressive schooling fish with a big personality. They will reach a maximum size of 3 inches which makes them a little larger than other GloFish. For this reason, you should only keep 3-4 GloFish Tiger Barbs in a 10-gallon tank.
GloFish Tiger Barbs are very active fish that like to form large schools, and they don’t always get along with other fish. They are known to nip the fins of smaller and slower fish, so when choosing tank mates for them care should be taken. They also prefer to live in a well-planted tank with lots of swimming space.
GloFish Tiger Barbs prefer slightly acidic water that stays between 74-79 degrees Fahrenheit. Overall a 10-gallon tank will be fine if you plan on only keeping 3 GloFish Tiger Barbs. But you might want to consider upgrading your tank if you want to have a larger school so you can provide them with the proper environment.
How many GloFish Rainbow Sharks in a 10 Gallon Tank
The GloFish Rainbow Shark (Order GloFish online at Petco.com) is the newest addition to the GloFish family. The GloFish Shark is one of the larger GloFish on the market. They can reach a maximum adult size of 6 inches. That means you can only realistically keep 1 GloFish Shark in a 10-gallon tank.
GloFish Sharks are a semi-aggressive fish that don’t get along with other sharks especially when kept in a small aquarium. They also need to be kept with tank mates that are larger than they are and fish that share a similar temperament. The GloFish Shark is a natural bottom dweller that will spend most of their time scavenging for food or eating plants and algae.
Even though it might be possible to keep a single GloFish Shark in a 10-gallon tank it isn’t recommended. GloFish Sharks are better suited for a 20-gallon tank, but a 55-gallon tank would be even better. If you really want a GloFish shark you can start them out in a 10-gallon tank when they are small, and then you can upgrade to a larger tank when they start to outgrow the smaller aquarium.
What kind of Tank do GloFish Need
Since GloFish come in a wide range of species there is no one GloFish tank setup that will work for all of them. If you stick to GloFish Danios and Tetras then a GloFish minimum tank size of 10 gallons will be sufficient. If on the other hand, you want to keep GloFish Tiger Barbs or Sharks a 20 gallon or larger tank would be better.
No matter what species you get, they will at a minimum need a tank with a filter and other accessories to keep them happy and healthy. And if you get any other GloFish besides the Danio, you will need a heater since all the other species prefer warm water.
And if you want the colors of your GloFish to pop, you will want to get a blue light to have the best results in your aquarium. Then to round out your tank you should get decorations and gravel that glows or fluoresces to tie the whole GloFish theme together.
