Wikipedia

Synodontis angelicus

Synodontis angelicus is a species of upside-down catfish commonly named polka-dot African catfish or angel squeaker. This species is native to the Congo Basin of Cameroon, the Democratic Republic of the Congo and the Republic of the Congo. This species grows to a length of 25 centimetres (9.8 in) SL although specimens up to 55 centimetres (22 in) SL have been recorded in nature.

In the aquarium[edit]

The polka-dot African catfish is mostly nocturnal. These catfish will excavate the substrate and may nibble plants. They eat smaller live foods and prepared foods. They prefer a water temperature of 22-28 °C, a pH of 6.5-7.5 and a hardness of 3-20 dGH.

Appearance[edit]

A variable pattern of creamy white spots of a constant size on a chocolate brown background characterises this catfish. The spots become less pronounced and the background grayer with age.
