I found a little information on these,
Very similar in habits to H. fasciatus, max size depends on who you believe, 9.2 cm.-14cm.,
Found only in Lake Bosumbi, Ghana, and the streams that feed it. a predator on small fish and inverts. One of the at least three fish sold as banded jewel fish. Likes 23-25 degree C. water, 7 ph, and a water hardness 15. A nest defending egg layer.
thats all I found.
