Four-banded Tigerfish - Datnioides polota Fish Profile & Care Guide
Introduction
The Four-banded Tigerfish (Datnioides polota), a ray-finned fish belonging to the family Lobotidae, is a striking predatory species native to the brackish waters of South and Southeast Asia. Renowned for its impressive size and magnetic presence, this species exhibits complex behaviours often perceived as intelligent, particularly when compared to many other fish species. Growing up to 30 cm in length, Datnioides polota requires a large aquarium to accommodate its size, maintain stable water conditions and minimise environmental stress. Its colouration is highly variable, typically displaying up to seven bold, dark vertical bars on a silver body, sometimes interspersed with one to four thinner, incomplete bars. A distinguishing morphological feature is the concave area of the back just in front of the dorsal fin's origin.
While juvenile Four-banded Tigerfish are relatively gregarious, adults become territorial and aggressive, necessitating careful stocking in captivity. They are best maintained as solitary specimens or in groups of six or more, provided the aquarium is large and equipped with ample visual barriers such as rockwork, driftwood, or mangrove root ornaments. This setup helps disperse group aggression, preventing any individual from being subjected to constant stress. As efficient predators, they will readily consume smaller fish, making selecting suitable tankmates such as similarly-sized Archer Fish, Monos, and Scats essential.
Four-banded Tigerfish require a spacious, well-filtered brackish aquarium with stable alkaline water parameters to ensure optimal health. A substrate of aragonite or crushed coral is recommended to help maintain pH stability. Their demanding care requirements and predatory nature make them a captivating choice for experienced aquarists seeking to house a unique and dynamic species.

Sexual Dimorphism
Sexual dimorphism in Four-banded Tigerfish is not readily observable through external characteristics, making it challenging to distinguish males from females based solely on appearance. However, a study examining the haematobiochemical profiles of this species revealed that males exhibit consistently higher levels of specific blood parameters compared to females. These internal physiological differences, while significant, are not discernible without specific medical testing.

Natural Habitat
The Four-banded Tigerfish (Datnioides polota) is native to Southeast Asia, with confirmed populations in Thailand (Songkhla Lake, Tha Taphap, and Chao Phraya Rivers), Vietnam (Mekong River Delta), India (Chilika Lake, Mahanadi, and Hooghly rivers), Bangladesh (Ganges River Delta) and Myanmar (Yangon and Salween rivers).
You can also find them in Singapore (Pulau Ubin), Indonesia (Batang Hari River in Sumatra, and the Sambas, Kapuas, and Barito rivers in Kalimantan, Borneo), and Malaysia (Perak, Bernam, and Melaka Rivers in Peninsular Malaysia, as well as the Sarawak and Rajang rivers in Borneo).
This species primarily inhabits brackish waters such as tidal lagoons and estuaries but can also be found in freshwater rivers and lakes beyond tidal influence. Its adaptability to different salinity levels allows it to thrive in various aquatic environments, though it is most at home in brackish conditions similar to its natural habitat.
Breeding
The reproductive habits of Four-banded Tigerfish are not well-documented, particularly in captive settings. In the wild, studies suggest that this species may engage in year-round spawning, releasing eggs in multiple small batches, a behaviour referred to as partial spawning. However, there have been no confirmed reports of successful breeding of these fish in aquarium environments. Consequently, detailed information regarding their mating behaviours, preferred spawning conditions, and parental care remains limited. Further research is necessary to understand the reproductive ecology of this species fully.
Diet & Feeding
The Four-banded Tigerfish is a predatory species that primarily feeds on smaller fish, crustaceans, and aquatic insect larvae in its natural habitat. In captivity, juveniles can be offered live or frozen foods such as bloodworms, small earthworms, and chopped prawns. As they mature, their diet can include larger items like strips of fish flesh, whole prawns, mussels, and larger earthworms. It's important to avoid feeding them mammalian or avian meat, as these can lead to health issues due to improper lipid metabolism. Additionally, the use of feeder fish is discouraged because of the risk of disease transmission and their generally low nutritional value. Adult Four-banded Tigerfish do not require daily feeding; providing food two to three times per week is sufficient.
