⚠️ Level: Intermediate — a decorative algae eater for the specialized, high-flow aquarium.

The Sewellia Lineolata, also known as the Tiger Gastromyzon or Saigon Algae Eater, is a fascinating and particularly decorative bottom dweller from the fast-flowing mountain rivers of Vietnam and Laos. With its striking tiger-like stripe pattern of gold and brown — unique to each individual — this fish is a real eye-catcher that also does an excellent job as an algae eater.

✂️ Care

Provide strong currents, high oxygen levels, and a substrate of smooth stones and driftwood — essential for this animal to thrive. Keep in a harem or group for the most natural behavior. Feed algae wafers, spirulina, vegetable snacks (cucumber, zucchini, spinach), and occasionally frozen food such as bloodworms or daphnia for extra protein.

🐠 Combination tip

Peaceful towards other species, although males can be territorial among themselves and perform impressive courtship dances. Combine with other coldwater-loving species in a Hillstream biotope.

❓ Frequently asked questions

Why does this fish need so much current?
Sewellia Lineolata comes from fast-flowing mountain rivers and uses its suction mouth to cling to rocks in the strongest currents — it also needs this behavior in the aquarium.

Is each specimen uniquely patterned?
Yes, the tiger-like stripe pattern is unique to each individual — no two Sewellia's are exactly alike.

Can this fish also live in cold water?
Yes, it prefers cooler water than most tropical fish, making it ideal for an unheated or lightly heated Hillstream aquarium.
