A low-end brackish setup with a specific gravity (SG) of around 1.005 to 1.008 is recommended for figure 8 pufferfish, as they thrive in this environment.

Frequent water changes, around 50% weekly, are essential to keep your figure 8 pufferfish healthy and happy.

Visually complex fish tank decorations, such as plants, caves, and rockwork, will provide your pufferfish with endless entertainment and exploration opportunities.

Plastic tubes similar to Habitrail's can also be a fun addition to your pufferfish tank, allowing them to swim through and explore.

The figure-8 pufferfish originates in the brackish streams and estuaries of Southeast Asia. This region includes Borneo, the Malaysian peninsula, Sumatra, and Thailand.

These fish thrive in areas with partial salinity, which is a unique environment that's different from full saltwater or freshwater.

The figure-8 pufferfish can be found in various parts of Southeast Asia, but they don't breed in captivity, so they're not as commonly kept in aquariums as some other species.

They do, however, have a relatively low risk of overfishing, which is good news for their populations.

Figure 8 puffers are small for pufferfish, reaching an adult size of fewer than three inches.

Their deep brown color on the upper portion of the body is a distinctive feature, with white on the underside.

Yellow spots and lines are sprinkled throughout the body, adding to their unique appearance.

The name figure 8 puffer is derived from the markings on the back of the fish, many of which resemble the shape of a figure 8.

A well-fed puffer can easily be spotted by its rounded belly, giving it a roly-poly appearance.

Their beak-like appearance is due to the upper pair and lower pair of teeth, each fused together.

Breeding the figure 8 puffer is a challenging task, with little known about the process. They are reported to lay eggs on a flat surface, such as the substrate.

The male figure 8 puffer takes on a crucial role in breeding, guarding the eggs for approximately a week until the fry are free-swimming.

Sexual Dimorphism is a key aspect of understanding the reproductive habits of certain species.

Adult females may grow larger than males, making it almost impossible to sex them by external means.

This can be a challenge for breeders and researchers alike, requiring close observation and sometimes even genetic testing to determine the sex of an individual.

Breeding and reproduction of figure-8 puffers can be a challenging and rare occurrence in captivity.

Little is known about how to breed figure-8 puffers, but on rare occasions, they have spawned in captivity and laid eggs on a flat surface, such as the substrate.

The male figure-8 puffer guards the eggs for approximately a week until the fry are free-swimming, showing some degree of brood care.

It's worth noting that not much is known about the breeding habits of figure-8 puffers, and they are not thought to have been bred in the hobby.

A 15 US gallon tank is the minimum size required for a figure 8 puffer, and it needs to be fully cycled before introducing the fish.

The ideal temperature range for a figure 8 puffer is between 24 °C and 28 °C, which is equivalent to around 75-82 °F.

Over-filtration is recommended to keep the water clean, and frequent partial water changes are necessary to maintain optimal water quality.

A substrate of crushed coral or aragonite sand is recommended to keep the pH at a steady level of around 8.

A specific gravity of 1.005 to 1.008 is ideal for figure 8 puffers, and it's best to use a fish-less cycling technique if you're bringing your puffer from a store in fresh water.

Regular water changes are crucial, with 50-percent weekly water changes being the best way to keep your figure 8 puffers healthy and happy.

Puffers are not well suited to a community aquarium because they tend to be aggressive.

Ideally, figure-8 puffers should be kept alone or in a large aquarium with only a few other fish that thrive in the same partial-salinity habitat.

Owners who have kept them in brackish water find that bumblebee gobies, knight gobies, and mollies are suitable companions.

Owners keeping them in freshwater aquariums have reported keeping them with fish such as barbs, "sharks", and tetras.

As a rule of thumb, don't expect to successfully keep them in a typical freshwater community tank.

A 15 US gallon tank is the minimum size for a figure 8 pufferfish, but a larger tank is always better.

Figure 8 puffers are warm-water tropical fish, so a temperature of around 78 degrees Fahrenheit is best for them. A temperature range of 24-28°C is also suitable.

A substrate of crushed coral or aragonite sand is recommended to keep the pH at a steady level. This is because puffers have no scales or gills covers and are extremely sensitive to toxins.

A fully cycled tank with no ammonia or nitrites and low nitrates (under 20 ppm) is essential for figure 8 puffers. This can be achieved with a fish-less cycling technique.

A low-end brackish setup with a specific gravity (SG) of around 1.005 to 1.008 is the best environment for figure 8 puffers. If kept in fresh water, their immune systems are compromised, causing disease and early death.

A hydrometer or refractometer is necessary to measure the SG of your tank water. This will help you adjust the salt levels to match the brackish environment.

Overfiltration is recommended for figure 8 puffers to keep the water clean and healthy. This can be achieved with a good filter system.

50-percent weekly water changes are the best way to keep your figure 8 puffers healthy and happy. This will help maintain the proper water chemistry and prevent disease.

Marine salt is necessary to buffer the pH and create a brackish environment. Use a hydrometer or refractometer to measure the salt levels and adjust them accordingly.

Puffers need a secure environment to thrive, so a sand or gravel substrate with plenty of live or plastic plants for them to hide in is a good idea. This will help reduce stress and prevent illness.

Puffers are naturally aggressive, even to their own species, so it's essential to provide plenty of hiding places if you plan on keeping multiple puffers in the same tank.

Individual behavior can vary greatly, but having a visually complex tank with many hiding spots will help keep your puffers happy and engaged.

Plants, caves, rockwork, and even plastic tubes can be great additions to a puffer tank, providing them with plenty of opportunities to explore and play.

Java fern and Java moss are excellent options for brackish plants that can thrive in a puffer tank.

Identifying the figure 8 pufferfish can be tricky, as they're often misidentified by suppliers and shops.

Many figure 8 puffers don't have an eight-shaped mark on their back, so don't rely on that alone.

The most common identifying marks are the black ocelli or two eyespots at each side of the puffer – one is in front of the caudal fin and one is below the dorsal.

Eyespots serve a purpose – they're meant to fool predators into thinking the wrong end is facing them, so they won't be approached from behind.

Biocellatus actually means eyespot, which is fitting given their function.

Figure 8 puffers only grow to around 3 inches in size, so if you hear of one that's much larger, it's likely a Ceylon puffer (T. fluviatilis), which closely resembles the figure 8 puffer in body pattern.
