Do you want to make your own beautiful aquarium and add something new to your interiors?

To help you out, we have listed here a complete buying guide of the 29-gallon fish tanks, a detailed process of setting them up and their proper maintenance.

As the name suggests, a 29-gallon fish tank holds a middle ground, that is, not too small and definitely not too large.

So anyone, from a complete beginner to a professional aquarium owner, anyone can manage this size easily.

The first step is to choose your ideal aquarium tank.


A 29-gallon tank often comes with a kit which will help you a lot while connecting the whole setup correctly.

It is helpful specially to the beginners as they have no idea which equipment will go with what size (if they are planning on buying the equipment separately). So in such cases, kits come handy.

Since a fish tank is the first and foremost thing required for setting up an aquarium, here check out my personal top 5 picks among 29 gallon tanks below..

The heater helps to regulate the temperature of the water in the tank. A constant water temperature is important for the aquatic animals to feel comfortable and safe in their surroundings and reduces the chances of sudden death of the fish. 

The top quality heaters available for a 29-gallon tank are:

  • Ultimate safety and reliability. Integrated thermal protection circuitry prevents heater from overheating. If you forget to turn it off, the neo-therm will automatically shut it down.

After purchasing all the necessary stuff for a 29 gallon fish tank, you have to start the set up procedure.

The first step in setting up a 29 gallon tank is to clean the tank with warm water. Keep in mind not to add tap water to the tank as it contains chlorine which may be harmful for the fish.

Dechlorinate it with a solution available in the market.

Now that you have added water, it is finally the time to add aquatic animals like fish and other creatures to the tank.

Do not introduce the fish directly to the tank as the slight change in water temperature could kill your fish.

You need to be very patient and follow the strict directions on how to add the fish without shocking them.

Visit our website to learn about the procedure.

Here are some of the fish species that can keep in a 29-gallon fish tank:

  • Angelfish- These small-sized fish species are very calm companions making them a great pick for a 29-gallon aquarium. 
  • GouramiA pair of Gouramis including Three-Spot Gourami or Pearl Gourami would be an ideal choice as their size is small; or you can keep a group of Kill Fish and Pencil Fish
  • Dwarf Cichlid– Cichlids like Angel Ram Cichlids, Apistogramma Borelli Opal, Bolivian Ram, Colorful Gold and Electric Blue Dwarf Cichlids are ideal for a 29-gallon tank and you can keep a lot of them. 
    • Note: Oscar fish are not ideal for a small tank like this. 
  • Tetras– Tetra species like Red Neon Tetra, and Cardinal Tetra, Rummy Nose Tetra and other small species can be kept in the fish tank. 
  • Other fish species that could be placed in this tank are Betta Fish, a single Krib, a school of Harlequin Rasboras, Loaches, Plecos, Pygmy Cories, Catfish species, Guppies, Platies and Mollies


The last step is to look after your fish and tank. With fish, you need to be more vigilant as they can sense even the subtle environment changes which can kill them.

Spend some quality time with them and built strong companionship.

Do not forget to clean the tank every now and then. Cycling is also an important step as it encourages the growth of good bacteria and nutrients for your fish.

Pump the water for a better, clearer and cleaner environment.

Feed your fish from time-to-time and change the water at regular intervals.
