The Sewellia Lineolata, also known as the Tiger Gastromyzon or Saigon Algae Eater, is a fascinating and exceptionally decorative bottom-dweller from the fast-flowing mountain rivers of Vietnam. With its striking tiger-like stripe pattern of gold and brown, this fish is a true eye-catcher that also does excellent work as an algae eater in your aquarium.

Ideal Conditions:
The Sewellia Lineolata thrives best at a water temperature between 20-24°C and a pH value of 6.5-7.5 — cooler than many other tropical fish, making it ideal for unheated or lightly heated aquariums. An aquarium of at least 60 cm with strong current, high oxygen levels, and a substrate of smooth stones and driftwood is essential for this animal to thrive optimally. Keep them in a harem or group for the most natural behavior.

Diet:
As an omnivore, the Sewellia Lineolata enjoys grazing on algae and biofilm that grow on stones and decorations. Supplement their diet with algae wafers, spirulina, vegetable snacks (cucumber, zucchini, spinach), and occasionally frozen foods such as bloodworms or daphnia for extra protein.
