Eastern bottlenose mormyrids and others

Congo tetras in the background. Not sure about the 2 fish in the front next to the mormyrids

Those fish in the front may be Hemichromis cichlids, perhaps H. lifalili. I can't be sure, though.

Hemichromis guttatus
Hemichromis sp. “Blue Jewel”
Gnathonemus petersii

The true Hemichromis lifalili has never been exported (at least in great numbers) for the trade, and since most of the species found in River Wonders are actually found in the local ornamental fish trade (and I believe most are acquired that way), it’s safe to say that the Jewels are H. guttatus.
