Bryconalestes

The long-finned tetra, Brycinus longipinnis, is an alestid characin from West Africa, found from Gambia to the Democratic Republic of Congo and Gabon. It inhabits large rivers and, unusually for the genus, also moves into smaller streams and lightly brackish estuaries. Not imported often, it ships poorly but usually proves hardy once acclimatised, though it is very sensitive to deteriorating water conditions.
