Overview
Martorell's barb is a small, peaceful barb from west-central Africa that suits a planted community tank. It is easy to keep.
Did you know
Martorell's barb was once filed under the giant catch-all genus Barbus, like most of west-central Africa's little barbs. It moved to Enteromius only recently, and that genus now holds several hundred small African species.
Caring for the Martorell's barb
Keep Martorell's barbs in a group of at least six, in a planted tank of 24 gal (90 L) or more. Add driftwood and some leaf litter, and leave clear swimming lanes. Gentle to moderate current and some shade from plants or wood suit this stream fish.
This barb is soft-water by nature and does not fare well in hard water. Keep it at 72 to 81°F (22 to 27°C), with a pH of 6.0 to 7.5 and soft to moderately soft water. It is an unfussy omnivore that takes flake, small pellets and frozen foods readily.
Martorell's barbs are peaceful, active schooling fish for the middle of the tank. They settle in beside other African species such as Congo tetras and kribs without trouble. Aquarium breeding is not documented, though small barbs of this kind are generally egg scatterers.
Good to know
Enteromius martorelli is a member of the carp family, Cyprinidae, and one of the many small barbs of the Lower Guinea forests. It is silvery gold, with a dark line along the flank.
In the wild
Martorell's barb comes from the forest streams and rivers of Lower Guinea in west-central Africa, across Cameroon, Gabon and neighboring drainages.
