Type Locality: Swamps between Agwarba and Akwa, southern Nigeria
The habitat is swampy areas of small streams and rivers primarily around the Niger River delta.
While sympatric with E. fasciatus togolensis, the two species accupy different biotopes. E. longiventralis prefers the edges with vegetation while E. fasciatus togolensis is found in open water.
Breeding of this species is not difficult. Floating mops work fine and most eggs are found near the top. Eggs do well in separate small containers and usually take 10-14 days to hatch. Fry will take newly hatched brine shrimp immediately.
