Overview

The Brazilian ram is a small, warm-water dwarf cichlid, kept much like a Bolivian ram. It is a step up from the easiest fish.

Did you know

The Brazilian ram, formally named in 2022, was the first new member of its genus in more than seventy years. Until then the ram genus held only two species, the common ram and the Bolivian ram.

Caring for the Brazilian ram

Keep a bonded pair of Brazilian rams, or a small group in a larger tank from which a pair will form. A pair needs at least 14 gal (54 L), planted and softly filtered. Give them a soft sand floor, driftwood, some plants and gentle flow.

Hold the water at 77 to 86°F (25 to 30°C) and a pH of 5.5 to 7.0. The upper end of that temperature range suits it well. Feed small foods such as quality flake and micro pellets, frozen bloodworm, brine shrimp and daphnia.

The Brazilian ram stays near the bottom and holds a small territory. It is peaceful but will defend a spawning site, so pick gentle tank mates.

It is a substrate spawner. A pair cleans a flat stone or leaf, then guards the eggs and fry together. Breeding it takes a little experience.

Good to know

Mikrogeophagus maculicauda belongs to the cichlid family, Cichlidae. Its name means spotted tail, for the dark blotch at the base of the tail. That blotch and a green body sheen separate it from the Bolivian ram and the common ram.

In the wild

Mikrogeophagus maculicauda comes from the upper Rio Guapore in Brazil. It lives in warm, clear, slow tributaries over sand, with wood and leaf litter, in soft to neutral water.
