Overview
The tri-band sumo loach is an aggressive bottom fish for a tank with current and caves. It needs a keeper with some experience.
Did you know
The tri-band sumo loach was traded for years as a color form of the sumo loach. It took DNA work published in 2023 to make its third band official.
Caring for the tri-band sumo loach
Give the tri-band sumo loach a river-style tank of 24 gal (90 L) or more. Add current, cobbles and a cave that it can own. Keep the temperature at 72 to 79°F (22 to 26°C) and the pH at 6.5 to 7.5. Feed it meaty sinking foods, which keep it content.
Like the sumo loach, it is a one-per-tank fish unless the aquarium is large and broken into many territories. It is aggressive and bullies its own kind and similar bottom dwellers. Keep robust midwater fish above it, and choose any tank mates with caution.
