Mount Cameroon, in the Kaké River system & the northern area of Fernando Poo (currently named Bioko) in the Rio Consul drainage (this island population may or may not belong to A.volcanum). The eastward frontier appears to be the Mungo River. In the west it is Ekondo Titi. Here A.bivittatum takes over. Collecting sites are found on level volcanic rock & sedimentary substrate (Bakundu). |

Breeding Notes |
Regarded as a more difficult member of the subgenus. Males can be aggressive & plenty of cover should be provided for the female (s). Parents can be predatory towards young so it's better to take the eggs out frequently & hatch in a seperate container. Water incubation takes 12-14 days. Sexual maturity is attained around 6-7 months. Oliver Legros reports in BKA newsletter No.329,
February 1993 that sex ratio is biased towards males. His Kumba - Kaké
fish were lost due to this. |
