Many large-bodied fish species can fit in a small tank.
A 6-month-old fancy goldfish can be just 2-inches long but will grow up to be 6-inches long as an adult. Nano fish, which grow no more than 2-inches long as adults, are the smallest fish in the world. Nano fish are also known as “miniature fish” because they are so small that they can fit inside a standard aquarium.
They are often used in aquaria as a way to keep small fish such as snails, crayfish, and other small invertebrates in larger tanks.

What is the minimum tank size for guppies?
We recommend a 5-gallon aquarium for a trio of guppies because they grow to be an average of 2 inches long. A 10- or 20-gallon aquarium would be more appropriate in most cases. They also need to be able to swim freely in the water, which means a tank with a shallow depth of at least 6 inches. The best way to keep a pair of gouramis is to have them in a group of three or more.
If you have a larger tank, you may want to consider adding a second pair to the group, but it’s not necessary. You can also keep two pairs in one tank if you want, though this is not recommended as it can lead to overcrowding. Keep in mind that you can only keep one pair in your tank at a time.

This will allow you to get a feel for the size of your tank, and will give you a good idea of how much water you will need to add to the tank to maintain a healthy guppy population.
If you decide to go larger than 5 gallons, you may want to consider using a larger filter to help keep the water clean and prevent algae growth.

The general rule of thumb is one gallon for every one inch of fish. tank. You can keep three males in an aquarium of this size. When it comes to females, you can keep two, but experienced people can push that number up to three.
If you want to keep more than three females in the same aquarium, then you will need a separate tank for each of them. If you don’t have any of these things in place, it will be very difficult to maintain a healthy guppy population.
Can bettas live in a 3 gallon tank?
Most shallow 3-gallon tanks with a water depth of less than 6 inches need to be custom made. The height of a good-sized commercial tank is between 10 and 12 inches. It’s not a good thing if the water levels are made deeper by anything over 12 inches. If your tank is too shallow, it will not be able to keep up with the growth of your fish.
If you are using a shallow tank, make sure that your water level is at least 6 inches above the bottom of the tank. You will also want to add a layer of gravel or sand between the gravel and the substrate, to help prevent algae from growing on the sand.

You’ll also need to consider the size and shape of your aquarium, as well as the type of lighting you will be using.
