C. micropeltes is also referred to as 'Indonesian', 'red', or 'redline' snakehead, the latter names in reference to the appearance of juveniles which often appear in the ornamental trade despite its unsuitability for home aquaria. It is somewhat hyperbolised in the media as a fearsome, invasive "monster" fish with a reputation for killing more fish than it can eat, and even the occasional human, although in reality...

One of the most invasive fish species in the world, O. mossambicus is one of the species farmed for supermarkets and restaurants across the globe. Several colour varieties have been selectively bred from the natural green fish to make the fish more appealing to consumers and unsurprisingly, it is these more brightly coloured forms which are usually seen in aquaria. Some of these variants are cross breeds with other species of Oreochromis. The destructive effect of O. mossambicus on non-nativ...

One of the most invasive fish species in the world but also one of the most economically important, O. niloticus is bred in huge numbers in many countries as a food fish. It is often cross-bred with other Oreochromis species for colour in order to make the fish more appealing to consumers. The destructive effect of O. niloticus on non-native ecosystems into which it escapes or is released is mainly due to it's adaptibility. It has been recorded over a temperature range of 60-110°F an...

The majority of original populations have already been extirpated due to introduction of invasive species such as Gambusia holbrooki and Poecilia reticulata, ongoing deforestation of the Ambohitra Massif, and physical diversion of the source of the Sakaramy River for domestic use by locals. An additional population may exist in a stream on the southern slope of the Ambohitra Massif on the road between Bobasokoa and Anivorano, near the village of Andranotohiliny, but this requires verification.
