Overview
Dwarf hoplos are small, peaceful and hardy catfish for the bottom of a planted tank. They are easy to keep.
Did you know
Dwarf hoplos can breathe air from the surface. That lets them survive in warm, stagnant pools that would suffocate most fish.
Caring for the dwarf hoplo
Dwarf hoplos are social, so a group suits them, though one also does fine alone. Give them 24 gal (90 L) or larger, with soft sand and plenty of plants and cover.
Keep the water at 68 to 75°F (20 to 24°C) and a pH of 6.0 to 7.5. They are hardy and forgiving of poorer conditions. Feed sinking pellets, frozen bloodworm and other meaty sinking foods.
Dwarf hoplos are peaceful and safe with other community fish. At spawning time, the males build and guard a floating bubble nest. Breeding them is a medium challenge.
Good to know
Dwarf hoplos are armored catfish of the family Callichthyidae, in the same subfamily as the larger hoplos. Their dark brown bodies are dusted with small black spots. The species is listed as Lepthoplosternum pectorale and also known as Hoplosternum pectorale.
In the wild
Dwarf hoplos are a southern species, unlike their Amazon relatives, and are restricted to the Paraguay and Chaco region. They live in slow, weedy waters of the Paraguay basin, often in oxygen-poor pools and marshes. There they forage over soft bottoms among plants and leaf litter.
