STEP 2: BUYING THE RIGHT STAND

Now that you have purchased the tank, you are just a few steps away from officially becoming a fishkeeper and joining thousands of fish owners around the world who are already enjoying this wonderful hobby.

In this step, you have to buy a stand suitable to the shape of your tank.

Aquarium stands are a must for large and medium sized aquariums. If you do not have a furniture with smooth surface, you might be needing a separate stand for it. It not only makes the aquarium looks even better but it also keeps it safe.

Following are my favorite stands for a 37 gallon fish tank:

STEP 3: MAKING THE TANK READY

After the first two steps, it is time to move on to the next which is making the tank ready.It means that you have to clean the tank thoroughly, inside and out.

But remember to not use harsh chemicals while cleaning the inside of the tank, as it might harm the fish.

Another step is to wash the aquarium gravel, rocks and ornaments with warm water. Make sure to clean them more than once as they form an important part of the aquarium.

Here are some factors that will work towards deciding the kind of GRAVEL you should put in your tank:

Fish help you decide the kind of gravel you need and how much of it. Some fish prefer coarse gravel where they can mess around, while some prefer finer gravel where they can dig around and forage in.

Big-rooted plants require a deep layer of finer gravel because they need a lot of nutrients from it. Plants with small roots can do with a shallower layer of coarse gravel.

The size of your tank is another determinant of the amount of gravel you need.

Some substrate for planted aquariums are:

STEP 4: FILLING THE TANK WITH WATER

Now you have to pour the water onto a plate or saucer sitting on the gravel, to keep it in place. Remember to add a water conditioner to dechlorinate the water.

Then, by using an aquarium-check valve, locate your air pump underneath the tank. Add live plants after warming the water with a heater. You can also use an aquatic plant fertilizer for the purpose like:

Now add the rest of the water, leaving some air space between the water and the cover.

STEP 5: ADDING FISH

Some fish species are calm while some are active. It depends on you, what type of environment you want to create in your tank. So choose the species accordingly.

The fish species you want to have in a 37 gallon aquarium, depends on the environment you want to create and the kind of stuff you have placed in the tank.

  • ANGELFISH is one species that you can keep in a tall and rectangular 37 gallon aquarium. I would recommend you to keep just one of them, otherwise it would be fighting with other Angelfish.
  • HONEY GOURAMI will be my another recommendation as it grows only about 2-2.5 inches at max. Also, you can keep a shrimp around them, as they do not prey on them that much. Prefer to keep a FEMALE GOURAMI over the male ones, as they are not as aggressive.
  • APISTOGRAMMA is also a great pick as it is  adaptable to any environment and goes well with lots of school fish. You can keep 20 or more of them.
  • BOLIVIAN RAM as they grow 3 inches at max and BETTA, as they can easily survive in the size of a 37 gallon and are not at all aggressive.

For a riverine community set up in a 37 gallon aquarium, here are two examples:

CALM SPECIES

  • 6 Hatchet fish for the Top
  • 8 Glass Catfish for the Middle
  • 8 Kuhli Loaches for the Bottom
  • A pair of Pearl Gourami for the Center
  • Nerite Snails

ACTIVE SPECIES

  • 6 Rummynose Tetras for the Top
  • 10 Celestial Pearl Danios for the Middle
  • 6 Dwarf Corydora Catfish for the Bottom
  • A pair of Keyhole Cichlids for the Center
  • 6 Otocinclus Catfish

Congratulations! As you have completed the process of setting up a 37 gallon aquarium!

Now feed your fish and enjoy watching it move about in its new home!

NOTE: There is a particular procedure that needs to be followed while adding a fish to a new tank. It is not just about placing the fish in the water.

Everything needs to be done carefully. If you want to know more about it in detail, check our website.

STEP 6: MAINTENANCE

Work is never 100% complete with an aquarium. It is always half done!

When you have set up the aquarium, it is time for its time-to-time maintenance. Proper fish care is essential for their well-being.

It means more than just feeding the pets or putting everything necessary in the right place inside the tank.

Spending just 30 minutes in a week, on aquarium maintenance can prevent many common and consuming problems.

I will advise you to spend at least 30 minutes with your pet, in a week. I know these creatures are not very demanding, but they do require care.
