What Should You Know About Caring for Your Spotted Congo Puffer?


Pufferfish are known to have bold personalities and prefer to live in solitude when kept in an aquarium. They typically inflate when stressed or threatened, so if you notice your puffer inflating in its tank, keep a watch for likely reasons.

Such behavior can be attributed to physical changes to the tank configuration, volatile water parameters, or external stresses. Having sharp objects can potentially injure your Spotted Congo Puffer, making the aquarium an unsafe habitat for them.

To safeguard against predators, pufferfish inflate their stomachs with water or air. This species originates from Congo in Central Africa and is even present in rivers with a considerable flow. Often you will find Congo puffers buried in the soft substrate and waiting to pounce on their prey.

Care Guide

The spotted variety, when mature, grows to four inches in length. Should you choose to add this breed to your fish collection, carefully follow the enumerated care guidelines:

Tank Size

This puffer species requires a reasonably sized aquarium that can hold a minimum of 40 gallons of water. By incorporating hardy plants, cured driftwood, and rock cave formations into its tank, you replicate their natural conditions.

The presence of sandy substrate allows the Spotted Congo to wait in hiding for its prey. For this purpose, cover the aquarium with a thick layer of soft substrate. Three to five inches deep substrate enables the puffer to bury itself completely.

Tank Maintenance

Since puffers are messy eaters, the waste they generate adversely affects the tank’s water parameters. Moreover, Spotted Congos are extremely sensitive to deteriorating water conditions as they contract diseases and bacterial infections. Regular tank maintenance keeps your pet fish happy and healthy.

It involves replacing half the water every week, having a reliable filtration mechanism in place, and substrate vacuuming. You can maintain tropical water conditions by keeping pH levels neutral between 6.5 to 7.8 and a steady temperature of 75 to 82 degrees Fahrenheit.

Mate Compatibility

Being a predatory fish, the Spotted Congo sets up territories and eats those who intrude into its space. They have unique hunting styles and use their sharp teeth to cut through hard shells and tear meat. The Congo puffer has a tank mate compatibility that borders on zero.

Dietary Habits

Your Spotted Congo Puffer thrives on live food, and its feeding time gives you a peek into the fish’s natural behavior. Once they recognize you, their owner, they display active behavior in anticipation of the food. This puffer breed has a voracious appetite and relishes snails, worms, and crustaceans.

Feed your freshwater puffer on live or frozen food like fish and dried meat. Always source such food from a reputed source to ensure you feed your pet fish a nutritious and parasite-free diet. When younger, feed them daily, but you can give them a meal every other day as they begin to mature.

Considering Congo puffers are an aggressive breed and demand a spacious habitat, breeding them in captivity is a challenge. Placing a pair in one aquarium instead of encouraging breeding may result in death.
