Mbu Pufferfish - Tetraodon mbu : Complete Fish Profile & Care Guide

Table of contents

Introduction

Mbu Pufferfish (Tetraodon mbu) are a popular choice for experienced aquarists and for good reason. These charming fish have a unique personality that sets them apart from other species. They are known for their intelligence and ability to recognize shapes, and some have even been reported to recognize their owners.

With their expressive eyes and ever-present smile, Mbu Pufferfish make for an endearing pet. They are particularly fascinating to watch when they inflate, especially the more colourful sub-species. However, raising these fish can be quite challenging, which makes them a great choice for those who enjoy a challenge. Mbu Pufferfish are typically aggressive and are best kept individually in their own tanks. Their large size also means that they require a lot of space, and only experienced aquarists should attempt to raise them.

Despite being regarded as one of the comparatively more placid pufferfish species within the trade and hobby circles, careful consideration is paramount when selecting tankmates for the Mbu Pufferfish. Theses Pufferfish stand as a species characterized by heightened sensitivity and susceptibility to stress, even in light of its substantial size. While it generally seeks to avoid confrontations with other fish, particularly those surpassing it in size, the Mbu is not suited for inclusion in a predatory tank setting.

Considering its natural habitat, numerous larger fish species within it are either inherently territorial and aggressive or exhibit piscivorous tendencies. Through the process of natural selection, the Mbu has evolved to evade larger fish, thereby maintaining its safety. This intrinsic aversion to larger fish persists within captivity.

In line with these insights, it is strongly advised that Mbu Pufferfish owners refrain from cohabiting with aggressive, territorial, or larger fish, as well as those prone to frequent swimming near the puffer's head. The presence of larger fish occupying the upper regions of the tank can induce anxiety within the mbu puffer, potentially causing it to favour the lower sections of the aquarium for refuge. Optimal husbandry entails preserving the Mbu Pufferfish as the focal point of the aquarium, being the largest inhabitant. In selecting tankmates, a criterion of peacefulness, non-territorial behaviour, and moderate swimming speed should be emphasized.

For instances where water hardness remains below 15 GH, introducing medium-sized Congo Tetras as companions can be an advantageous choice. This addition serves a dual purpose, acting as a calming influence on the Mbu puffer's timidity while enhancing the keeper's experience through their shoaling behaviour. Congo Tetras exhibit a dietary behaviour that complements the puffer's feeding patterns, gathering small food particles released during the puffer's consumption.

Due to their potent bite, mbu pufferfish is not recommended for cohabitation with bottom-dwelling fish like corydoras. Although intentional harm is unlikely, accidental biting incidents are possible due to the puffer's formidable bite force. This ability to cause injury extends to other fish, warranting careful consideration of tankmate compatibility.

The Mbu puffer fish showcases a predominantly yellowish olive-green hue that transitions into a vivid gold shade along its flanks and caudal fin, accompanied by pale yellow underbellies. This colouring is complemented by an intricate dark pattern that graces the area immediately above this display. During their juvenile stage, these patterns manifest as modest brown spots or blotches dispersed across their yellow-green bodies. However, these subdued markings undergo a transformation as the Mbu puffers mature.

Upon reaching adulthood, the aforementioned brown spots evolve into a complex and labyrinthine design, spanning a substantial portion of their dorsal region. A noteworthy characteristic of these puffers is their scaleless nature, further contributing to their distinctive appearance. In stark contrast to their verdant bodies, these Pufferfish exhibit vibrant orange eyes that project laterally from their prominent cranial structures. Some observers perceive an aura of intelligence in their gaze.

The Mbu Puffers' vivid orange ocular organs boast exceptional visual acuity, regardless of whether they are actively observing their surroundings or not. Close observation might even unveil the occasional blink, underscoring their attentive nature. Among the remarkable attributes of the Mbu puffer fish, besides their intricate patterning and distinct eyes, is their remarkable dentition. Precisely, these Puffers possess four formidable teeth that are effectively amalgamated, crafting a mouth resembling a beak-like structure.

Natural Habitat

The Mbu Pufferfish originates from Tanzania, Zambia, Cameroon, Burundi, the lower and middle regions of the Congo River in Africa, as well as the east coast of Lake Tanganyika. The Mbu Pufferfish can be found in riverbanks with strong water currents, often in the company of submerged vegetation. Their ability to thrive in these challenging environments is a testament to their resilience and adaptability.

Breeding

There is no record of successful captive breeding of Mbu Pufferfish. A significant amount of water volume would be necessary to undertake a serious breeding attempt. Additionally, the difficulty in determining the sex of these fish renders breeding attempts challenging and may not justify the allocation of resources.

Diet & Feeding

The Mbu Pufferfish presents a challenging feeding regime for many aquarium owners. Their diet primarily consists of shelled foods, including snails, muscles, crayfish, and clams, which are crucial to maintaining healthy teeth, also known as a beak. Due to the positioning of their eyes on the sides of their head, these pufferfish require careful alignment with their food before taking a bite. A well-balanced diet should include shelled food five times a week, supplemented with softer foods such as frozen bloodworm, small fish, or cocktail shrimps for the remaining two days. Adequate nutrition is essential for optimal health and development of these fish.
