Origin: Jewels come from some of the west African rivers, not the Rift Lakes. Jewels kick bootie. Do not mix them with community fishes. We have here an African cichlid that mixes best with North, Central, and South American cichlids. In the wholesale listings, we find them listed with the American cichlids (ditto the kribensis). Jewels stand up to oscars twice their size. They cannot, however, stand up to Rift Lake cichlids. Mbunas skin ’em alive.
Name “Jewel” refers to the little iridescent sparklies (the maculatus or “spot” in their scientific name) that cover their bodies -- not their colors, and certainly not their personalities.
Spawning These little rowdies spawn about as easily as a Dempsey, but have fewer fry because they stay smaller. Jewels would spawn as easily as convicts if you could sex them as easily. You can’t tell the sexes apart by color or finnage -- even by size. You have no clue to their sexes until you see your pair defending a clutch of eggs. You pretty much have to let several of them pick their own partners. Put some ceramic (excuse me, they’re all resin these days) caves in a cichlid community tank and watch them whale on the Dempseys for possession. Put in several caves and rocks to avoid serious battles for spawning territories.
Conditioning Give your jewels a variety of foods to plump them up. Plump them up! Flakes and pellets first, then give them the right size frozen foods. Small earthworms contain secret secretions that puts a surge in their urge to merge. Ditto on mealworms snipped in half. You’ll see a change in color, belly size, and aggression level. If you see their breeding tubes appear, get ready to pass out cigars. Chances are, you’ll miss the whole process and find them protecting a patch of wigglers by the time you know what’s happening.
