Overview
What to know before you buy.
The Siamese Tiger Fish, also known as the Indonesian Tiger Perch, is one of the most strikingly beautiful predatory fish available to hobbyists. Its bold vertical black bars on a golden-yellow body create a visually stunning appearance. Originating from Southeast Asian river systems, this ambush predator is slow-growing and can be finicky about food, making it a challenging but rewarding species. Highly sought after by monster fish collectors for its beauty and rarity.

A minimum 700L aquarium suits Siamese Tiger Fish. Use robust décor and sight breaks so each fish can hold its own space.
