Other equipment like aquarium hood or a simple lid are important to protect the tank from any damage.

A gravel vacuum is useful in cleaning the substrate easily. Moreover, an aquarium pump helps in mixing up the water and enhancing the overall performance of filter. 


Clean your 30 gallon tank with warm water and then add dechlorinated water to it. Since it is not a big size, it will take a few minutes to clean.

Do not forget to cycle the tank every now and then, as it helps in building up necessary nutrients in the water and keeping the water clean. 


In this step, you need to add the fish to the aquarium tank. To know the detailed process about adding the fish into the tank, visit our website. 

You can create different types of aquarium environment like-community aquarium, species-only aquarium and Paludarium.

A community aquarium is a perfect fit for this tank size. Here you can create a beautiful community of a variety of fish, plants, and decorations. 

  • Fish to be kept in a community tank: 6 Cherry Barbs, 1 Pearl Gourami, Bristlenose Pleco
  • Fish to be kept in a species only tank: Scarlet Badis fish and others.
  • You can also create a Paludarium – it is a half aquarium, half terrarium that combines both terrestrial and aquatic plants or animals. 

Check out the list of fish species that you can put in a 30-gallon aquarium tank-

  • Cichlids(Dwarf, South African, and South American)
  • Tetras
  • Catfish species(Corys, Plecos, Otos)
  • Rainbowfish
  • Guppies
  • Gouramis
  • Rasboras
  • Mollies
  • Angelfish
  • Platies

Other creatures like shrimps, crabs, and snails could also be kept in the fish tank. 

Fish species should be chosen carefully as aggressive species put together could kill one another.

Therefore, you can keep small and peaceful fish. Semi-aggressive fish species are also a go-for in 30-gallon tank. 


Even though it is the end – you have successfully set up the tank, added water and fish into it, your responsibility doesn’t end here.

Tank maintenance is as important as any other steps. You must keep a vigilant eye on the behavior of your fish, if it is showing any disturbing signs.

That would tell you a lot and helps you maintain the tank for longer time without any issues. 

Clean the tank, cycle it, and feed the fish at regular intervals. Spend some quality time with your water buddies.
