Filter For 6 Gallon Fish Tank

When you first start a fish tank, it’s easy to feel overwhelmed by the number of different types of filters and equipment that are available. You might ask yourself: “Do I need a filter?” The answer is yes!

A filter removes all the dirt and debris from your water, which can cause illness in your fish. It also helps maintain the pH balance of your aquarium water so that ammonia doesn’t build up.

There are many different types of filters available today; however, some people prefer using a hang-on-back (HOB) filter for their six-gallon fish tank because they don’t take up as much space as other options like an under gravel filter or powerhead filter.

When choosing between HOBs, make sure to choose one with extra filtration so that your water stays cleaner for longer.

Types of Fish That Can Live in a 6-Gallon Tank


Tetras are small freshwater fish that come in many different colors. They are very easy to care for and can live up to ten years if well taken care of. The tank should be at least five gallons large with no gravel or plants because the tetra will eat them.

The tank should have an air pump and filter to keep it clean and healthy for the fish, as well as some sort of light bulb above the tank (so that there’s enough light for you to see). Tetras like tanks with open areas where they can swim freely but also places where they can hide away if needed.

Tetras originate from South America, so they prefer water temperatures around 77 degrees Fahrenheit. They are a type of freshwater fish that have been around for about twenty million years.

They belong to the characin family and come in many different species, including black neon tetra, cardinal tetra, gold barb, red-eye tetra, and more.

These tiny fish can be identified by their small size and thin bodies. The best way to care for these creatures is through proper feeding habits and an environment that promotes cleanliness.


Guppies may not be as large as goldfish, but they do require more space than other types of fish. Guppies are a type of fish that are extremely popular to have as pets.

They are very colorful and will usually get along with other types of fish in the tank, but they do need special care. Guppies can live up to two years, which makes them an excellent choice for beginner aquarists.

They prefer warmer water so it is important that you keep the temperature around 78 degrees Fahrenheit or else they may become ill.

The male guppy is always brighter than its female counterpart while pregnant females will be rounder and more plump looking than males after laying eggs because their bodies have been stretched out from carrying babies inside them!

You should feed your guppies several times a day to make sure they are getting enough food because if they do not, they will become malnourished and weak.


Platys fish is an incredibly popular, colorful aquarium fish that is relatively easy to care for.

These little guys can be found in a wide range of colors and patterns, so whether you are looking for something flashy or subtle, you should be able to find the perfect Platy for your tank.

With their fun appearance and low maintenance requirements, these beautiful creatures make great pets!


Mollies are freshwater fish that can live in both salt and fresh water. They have been popular pets for many years, especially among children because they are so small and easy to care for.

There are more than 40 different species of mollies – each with its unique appearance, which is why there is always something new to discover when it comes to this amazing fish!

Mollies make great companions for people who don’t want the commitment of caring for a larger animal like a dog or cat.

You can even teach them tricks! If you’re thinking about getting your first pet, but aren’t sure where to start, consider adding mollies into your life today!


Goldfish are known for their good temperament and can live in a 6-gallon tank. Goldfish are a type of freshwater fish that live in cold water. They can grow to be quite large, up to 10 inches long.

Goldfish have been bred for generations and come in many different colors. They are found all over the world but originally came from China before being introduced to Europe by the Romans around 200 AD.

Goldfish are very popular pets because they make great companions and can thrive both indoors and outdoors with minimal care requirements.

Corydoras Catfish:

Corydoras catfish or Cory Cat as they are commonly referred to is a small fish that belong to the family of Callichthyidae.

They can be kept in an aquarium with other community fish and their care requirements make them easily one of the most popular freshwater tropical fish kept by aquarists.

The name Cory comes from the Greek ‘Korion’ meaning helmet and Doras is Greek for skin; thus Corydoras means helmet-skinned (Callichthyidae).

Over 150 different species of this genus make it one of the largest groups in the order of Siluriformes.

Fish Size

When choosing a fish for your six-gallon tank, it is important to consider the size of the fish. A good rule of thumb is one inch per gallon however this may not work in all situations as some species require more space than others.

For example, if you were to fill up your six-gallon tank with neon tetras they would need at least two gallons each and even then they will be overcrowded which can lead to stress and illness.

On average you should plan on about 1-2 inches per gallon but if the species you are planning on getting is significantly bigger or smaller than the one inch per gallon rule, be sure to adjust accordingly.

Fish Temperature

When choosing a fish for your six-gallon tank it is important to consider their temperature requirements as well!

The optimal water temperature for most tropical fish is between 72-82 degrees Fahrenheit. If the water in your six-gallon tank gets colder than this it could lead to the death of your fish.

If you don’t have a heater for your six-gallon tank, or if you plan on going away for a while and will not be able to provide heat during that time, be sure to choose a species that can tolerate cooler water temperatures as well!

How Many Goldfish Can I Put in a 6 Gallon Tank?

The number of goldfish you can put in a 6-gallon tank depends on the water quality. Goldfish tend to produce more ammonia, which stimulates bacteria growth and is toxic to them.

For that reason, they are not likely suitable for a smaller tank with poor water quality or filtration, but better conditions may allow up to five goldfish per 6 gallons.

If you are considering getting four goldfish, make sure your aquarium is large enough – preferably 15 gallons or more with appropriate equipment.

Remember that these fish grow quickly! It might be wiser to only buy two at first if your tank is limited but imagine how much room those four will take up when fully grown!

If you have adequate space for one six-inch charm goldfish, you can technically put him with anything.

Since goldfish are active swimmers and require ample room to maneuver, it is recommended that you choose other active fish for your tank.

How Many Neon Tetras Can I Put in a 6 Gallon Tank?

It depends on a couple of variables, including the species and individual fish’s size. Certainly, you might be able to put around 5 or 6 neon tetras in a tank that is 6 gallons in capacity.

Generally speaking, the number of fish per gallon is between 1-2 inches in height within the fish tank.

To accurately determine how many neon tetras you could put into any given aquarium requires specific knowledge about the topography of what type or size of aquarium, how much filtration it has, container capacity, etc.

This information will give an accurate estimate of how many neon tetras can fit into your specified tank space satisfactorily without overcrowding or over-filtering.

Cost For 6 Gallon Fish Tank

As a hobbyist, I have been wanting to buy a 6-gallon fish tank for my saltwater aquarium. There are many different places where you can purchase a 6-gallon fish tank but they all vary in price depending on the retailer.

The benefits of buying locally include being able to see and touch the product before purchasing, as well as having someone knowledgeable answer any questions that may arise about caring for your new tank!

Fish Care Tips And Tricks For Beginners

The first thing that you need to do is clean the aquarium. This can be done with a siphon device and gravel cleaner, but it’s best to use an algae scraper for this job.

Once the tank has been cleaned, make sure any filters are running smoothly before filling up the tank.

Some people like to put some stress coat on their fish (especially betta) as soon as they get them home from the pet store.

It helps protect them from being stressed out by all of these changes in their environment, making them more likely to survive once settled into your home.

The last thing is finding a good location for your new addition! They should have plenty of room so they feel safe and not too cramped or overcrowded with other fish.

Common Problems of a 6 Gallon Fish Tank

Most of the issues that arise from a fish tank can be traced to one problem: poor water quality. This is because fish waste and uneaten food sink to the bottom, decomposing and using up oxygen as it rots.

In addition, if there are too many fish in your tank or if they are not fed properly, more ammonia will build up than your filter can handle. 

Most people who have problems with their aquariums do not realize that all of these issues come back down to this one thing: water quality.

If you want a healthy environment for your fish, make sure that you take care of them by keeping their water clean and free from excess waste and chemicals.

The list of the problems are:

  • The filter is too strong.
  • There are too many fish in the tank.
  • The water smells bad.
  • Fish are dying.
  • Algae is growing on the walls of the tank, which blocks light from entering and can make it difficult to see what’s happening inside.
  • The gravel is not washed enough and has a lot of dirt left over after being rinsed off with water.
