Dwarf Pufferfish (Carinotetraodon Travancoricus)

The Dwarf Pufferfish is one of the cutest freshwater species and the smallest Pufferfish in the aquarium hobby, and more hobbyists are starting to consider getting them.

Caring for these fish is easy once you know what you are doing, and their dynamic behaviour makes them interesting to observe.

But don't let the cuteness deceive you, Pea puffers are very feisty and sometimes aggressive, they have no issue in fighting with other species or each other. It's essential to give them enough space to feel comfortable and stay away from other fish.

Their bodies are relatively thick and dense looking. The front is slightly pointed at the mouth and gets most abundant near the middle of their bodies. When you reach their dorsal fin, their body gets thinner and stays about the same size through the whole of their caudal peduncle.

Dwarf pea puffers have tiny and modest translucent fins, creating an adorable effect that makes it look like these fat little bodies are being moved around by nonexistent fins.

Their dorsal fins are two-thirds down on their bodies, and their pectoral fins are pretty much right in the middle of their primary area of the mass. All of these fins are the same size.

They also have an impressive-looking caudal fin and caudal peduncle, and because it's quite clear and moderate in size, it can be hard to notice when you are watching these fish, making you think that they are swimming around with nothing.

Dwarf Pufferfish have a greeny-yellow body that extends all over, and they display dark spots that are spaced out consistently; however, they do not have these spots on their underbelly.

This species also has that classic pufferfish face with large eyes and an open rectangular-shaped mouth.

In the home aquarium, the Dwarf Pufferfish will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It can be slightly tricky to differentiate a male from a female.

Males tend to have a darker colouration with a dot or stripe on their belly, their bodies are more slender, and they display more aggressive behaviour in general.

In contrast, females are much plumper, slightly larger and have a yellow stomach.
