Overview
The dwarf distichodus is a peaceful shoaling fish for a roomy community tank. It is best with a little experience.
Did you know
The dwarf distichodus belongs to a genus that includes fish reaching well over half a meter and many times its weight. Those aquarium giants quickly outgrow home tanks, but this dwarf stays small enough to keep for life.
Caring for the dwarf distichodus
Keep dwarf distichodus in a shoal of six or more, since lonely fish grow stressed and sicken. A group needs a roomy tank of at least 30 gal (112 L). Leave open swimming room in the middle, with robust or floating plants around the edges and some driftwood.
Keep the water at 73 to 81°F (23 to 27°C), with a pH of 6.0 to 7.5. Like all distichodus, it is a dedicated plant grazer, and it grazes constantly, mostly on soft plant matter. Expect it to nibble and uproot tender plants, so hardy species, plastic plants or vegetables clipped in for it work better. Feed vegetable flakes and pellets alongside some frozen bloodworm and brine shrimp.
It is peaceful with other fish, so calm, sturdy tank mates suit it. There is no reliable record of it breeding in home aquariums.
Good to know
Distichodus decemmaculatus belongs to the family Distichodontidae. Its name means ten-spotted, for the row of small dark spots along each flank.
In the wild
The dwarf distichodus lives in the central Congo basin, including the wide waters of Pool Malebo. It keeps to vegetated margins with gentle flow.
