Overview
Paul Mueller's dwarf cichlid is a shy apisto for the bottom of a quiet, dim tank. It is a fish for a keeper past the beginner stage.
Did you know
In display light, the male's face sparkles as if someone dusted it with crushed glass. That sparkle is exactly how importers spot Paul Mueller's dwarf cichlid in mixed apisto hauls.
Caring for the Paul Mueller's dwarf cichlid
Keep a pair of Paul Mueller's dwarf cichlids in a quiet, blackwater-leaning tank of 16 gal (60 L). It wants a dim, structured setup with sand, leaves, wood and caves.
Give it stable warmth at 75 to 82°F (24 to 28°C) and a pH of 5.0 to 6.8. It takes small frozen foods well and dry food only occasionally.
Shyness is the main challenge with this mostly peaceful fish. Give it heavy cover and calm neighbors, and it comes out and shows its glitter.
Breeding is hard and follows the cave pattern. It works best in soft, slightly acidic, warm water, with small, frequent feedings for the fry.
Good to know
Römer and coauthors described Paul Mueller's dwarf cichlid in 2013 and named it for the German biologist Paul Müller. Males carry glittering blue-green scales across the face and shoulders over a soft gray body. It belongs to the same Loreto species swarm as norberti and allpahuayo. The members of that swarm are told apart by face pattern and fin shape.
In the wild
Paul Mueller's dwarf cichlid inhabits small lowland forest streams in the Iquitos region of Peru. It lives in soft, gently acidic water over leaf litter.
