Marakely

About

Marakely (Paratilapia polleni) is the sole surviving member of its genus and one of Madagascar's most iconic freshwater fish. The name 'marakely' translates roughly as 'black fish' in Malagasy, a nod to the deep, dark base coloration that sets off a scattering of iridescent spots across the body. Interestingly, there are both large-spotted and small-spotted forms in the hobby, and these should never be mixed since they hybridize freely. A real concern given how threatened this species is in the wild, where habitat loss and invasive competitors have pushed it toward the brink. In the aquarium, marakely are territorial toward their own kind and should generally be kept alone or as a bonded pair. Despite a reputation for aggression, they tend to be more measured with dissimilar tankmates that stay out of their space, though anything small enough to swallow will be treated as a meal. Breeding is possible and worth attempting given the conservation value, but the pair needs serious room and will claim a large stretch of the tank as their own. Brood care is involved and rewarding, with both parents guarding eggs and free-swimming fry for several weeks. This species is sensitive to abrupt shifts in water chemistry and prone to velvet disease, so consistent, gentle maintenance is essential rather than large infrequent water changes.
