Dwarf Pea Puffer Care

Dwarf Pea Puffer Tank Size

The minimum tank size for one Dwarf pea puffer is 10 gallons of the tank.

Active Dwarf pea puffer needs at least this space to live happily and healthily. Because of that, we can recognize this fish as a Nano aquarium fish. 

However, if you can possibly provide more space to give them the best habitat, I recommend 20 or 30 gallons.

Keep in mind that the space you provide to live them makes a big difference in your fish’s health and quality of life. 

Anyhow, do you wish to keep more than one Dwarf pea puffer? Add additional 5 gallons for each new fish.

How Many Should Dwarf Pea Puffer Be Kept Together?

Generally, it is ok to keep the Dwarf pea puffer alone.

But Dwarf pea puffers do better when they live as a group. Therefore, it should keep at least 3 Dwarf pea puffers together in a tank. 

Additionally, you already know male fish are aggressive and more territorial. So, it is better to keep one male with multiple female Dwarf pea puffers.

However, if you keep male Dwarf pea puffers together, I advise separating them during the breeding season. 

Tank Setup

Dwarf pea puffers live in rivers and lakes in the wild. Plus, they are widespread in very heavily planted areas.

Therefore, it is better to grow live plants in your tank to mimic their natural habitats. Also, live plants give a natural feeling to your aquarium, and they will add tremendous value to it. 

So, what plants can we choose for your Dwarf pea puffer tank? It is best to add hornworts, java moss, or floating live plants. 

In addition to that, you can add rocks, driftwood, and creating caves in the tank is more beneficial to make a secure feel for them. Also, these are creating hiding spots and places to explore them.

So, how about the substrate of the Dwarf pea puffer tank? 

You know, Dwarf pea puffers prefer to live in planted tanks. Therefore, you should choose the substrate that helps to grow plants well. That’s why sand and fine gravel are ideal for the tank. 

Plus, you can add aquarium soil that encourages plants to grow better. However, it means that choosing a suitable substrate is very important to setting up a planted tank. 

Generally, in the wild, Dwarf pea puffers commonly live in water areas of rivers and lake water and banks that have slow-flowing. Therefore, setting the water flow at a lower level in your tank is wise. 

Other essential things are lighting and the filter system. Always keep in mind to go with a high-quality filter because it directly affects the water quality. Dwarf pea puffers do well with diffuse light.  

Water Quality Condition

Dwarf pea puffers are very sensitive to any changes in water conditions. So, maintaining below water conditions is very important at an ideal level. 

Water temperature 

It should be between 72 to 82 Fahrenheit 

Water hardness

It is vital to keep water hardness at 5 to 15 KH. 

pH level

You have to maintain the pH level of the Dwarf pea puffer tank at 7 to 8. 

As a fish keeper, I recommend getting a reliable testing kit. Because it will help you ensure that your Dwarf pea puffers live in a healthy environment. 

In addition to that, performing water changes is an ideal way to maintain the tank’s water quality.

Mainly this doubt comes within the early stage that you are going to breed your fish. 

Suppose you have a tank half the size of a regular tank. It means you should have at least 5 gallons tank. Do not misunderstand; this tank size is the minimum size for one male and one female. 

When it turns to water conditions, you should maintain above mention water parameters as it is except for water temperature.

Increasing the water temperature to the higher end of the recommended range is better. It means to aim the water temperature at 79 to 80 Fahrenheit. Also, live plants are a better addition to your breeding tank. 

Further, do not forget to set a sponge filter in this tank unless fry will suck into the filter. 

So, create this type of ideal environment that motivates them to breed and wait. When the Dwarf pea puffer pair is ready to spawn, the male fish tend to chase the female fish, and once the female fish accepts his advance, the female fish lay the eggs in thick vegetation. Soon after, male fish fertilize the eggs. 

Then what you should do is, remove the parents from the breeding tank. Generally, eggs take around 24 to 48 hours to hatch and release baby Dwarf pea puffers.
