What makes the Siamese tigerfish appealing to aquarists?

Its distinctive coloration and dynamic presence make it a standout addition to large aquariums.

Is the Siamese tigerfish suitable for beginners?

Due to its size and care requirements, it's more appropriate for experienced aquarists.

Care and Environment

Proper care of the Siamese tigerfish involves attention to tank size, water parameters, and diet to ensure a healthy environment.

What is the minimum tank size for a Siamese tigerfish?

A single adult requires a minimum of 450 liters (approximately 100 gallons) to accommodate its size and swimming needs.

What are the ideal water parameters for this species?

Maintain a temperature between 22–26°C (72–79°F), pH levels of 7.0–7.5, and medium hardness to replicate its natural habitat.

What type of filtration and tank setup is recommended?

Use a robust filtration system to handle the biological load and provide open swimming spaces with some submerged wood or rocks for hiding spots.

What should be included in the Siamese tigerfish's diet?

Offer a variety of meaty foods such as shrimp, prawns, mussels, and fish. Juveniles can be fed bloodworms and brine shrimp. It's advisable to wean them onto dead foods to avoid the risks associated with live feeding.

Are there any specific challenges in keeping Siamese tigerfish?

They are sensitive to water quality and require regular maintenance. Additionally, their predatory nature means they may view smaller tank mates as food.

Origin and Habitat

The Siamese tigerfish is native to the Mekong and Chao Phraya river basins in Southeast Asia, including countries like Thailand, Laos, Cambodia, and Vietnam. It inhabits freshwater environments such as main rivers, tributaries, and connected lakes, often preferring areas with submerged wood and rocks that provide ample hiding spots. These regions typically feature warm temperatures and moderate water flow, conditions that should be mirrored in captivity to promote the fish's well-being.

Where is the Siamese tigerfish naturally found?

It is endemic to the Mekong and Chao Phraya river basins in Southeast Asia.

What type of environments does it prefer?

Freshwater rivers and lakes with submerged structures like wood and rocks.

Temperament and Compatibility

The Siamese tigerfish is a predatory species that can exhibit territorial behavior, especially as it matures. While generally peaceful with similarly sized fish, it may prey on smaller tank mates. Therefore, it's crucial to select compatible companions.

Is the Siamese tigerfish aggressive?

It can be territorial and may exhibit aggression, particularly towards smaller or similarly sized fish.

What are suitable tank mates for this species?

Large, robust fish such as larger cichlids, barbs, and other predatory species that can hold their own are appropriate companions.

Should Siamese tigerfish be kept alone or in groups?

They are typically solitary and may become aggressive toward other fish, especially as they mature. Keeping them singly is often recommended unless the tank is exceptionally large.

This distinctive coloration not only makes it a favorite among aquarists but also serves as camouflage in its natural habitat. Despite its popularity, the species is classified as Critically Endangered due to overfishing and habitat destruction, leading to its extirpation from certain regions like Thailand. Conservation efforts are ongoing, including attempts at captive breeding to preserve this remarkable species.

Why is the Siamese tigerfish considered endangered?

Overfishing and habitat destruction have led to significant population declines.

What makes its coloration significant?

The bold stripes provide camouflage in the wild and contribute to its popularity in the aquarium trade.
