At a glance the quick version
Looks how to spot one
Laterally compressed labyrinth fish
An oval, flattened fish with long thread-like pelvic fins, covered in a fine mother-of-pearl dotting over a silvery-brown base and a dark line running from the head toward the tail.3
Personality what they are like
A gentle, unhurried fish that suits a peaceful community; males can be a little territorial with one another, especially when nesting.2
Daily activity how busy a day looks
Glides slowly in the upper and middle water, often coming to the surface to take a breath of air.12
Grooming and care the hands-on bits
Keep the water clean and warm with a lid to hold humid air above the surface; plenty of plants and floating cover help it feel secure.21
Home where they are happiest
At least a 90 x 30 cm base (about 80 litres), densely planted with floating plants and gentle flow. Temperature about 24-30 C, pH 5.5-8.0, hardness around 2-30 dGH.21
Food basics what goes in the bowl
An easy omnivore that accepts most foods: quality dried food plus small live or frozen foods.21
Company who they like around
Peaceful with calm tankmates; keep one male with several females, or a group in a larger tank.2
The story where it all began
Dutch ichthyologist Pieter Bleeker described it in 1852 from a fish collected at Palembang, Sumatra, honouring his colleague J.M. van Leer. It has long been a favourite community fish in planted aquariums.3
