The total length of representatives of this genus ranges from 8 to 14 cm. The head is large, slightly flattened. The mouth is wide, the eyes are small. They have 3 pairs of antennae. The body is strong, narrow stripes of bone plates are located on the sides. The dorsal fin is large, starting with a stiff and sharp spike. The pectoral fins are wide, with large spikes. Adipose fin small. The anal fin has a short base, rather long. Caudal stalk narrow or wide.
Found in wetlands with slow flow or stagnant water. Mostly these are small river tributaries with vegetation. Prefer sandy-silty soils littered with snags. Pectoral fins make sounds of various volumes, reminiscent of a rattle. The spines of the dorsal and pectoral fins contain weak poison . Active at night, feed mainly on aquatic invertebrates , less commonly fish.
Distributed in the Amazon , Rio Negro and Essekibo river basins .
For maintenance use aquariums from 150 liters with a large bottom area. Fine sand of dark tones is poured at the bottom. As shelters, you can use large branched snags. From the vegetation, echinodorus bushes with a strong root system are suitable. Plants floating on the surface of the water - salvinia , duckweed , will not interfere.
Loving. Contain can be a group of 3 individuals or alone. Get along well with related species and other fish. They themselves are not afraid of anyone thanks to the powerful and durable “armor”. They feed on any food for aquarium fish, but give preference to live food. They don’t get used to dry food right away. Of the technical means, an internal low-power filter will be needed to create a weak current. The temperature is between 20-25 ° C.
