Common Whiptail Catfish

About

The Common Whiptail Catfish (Rineloricaria eigenmanni) is one of the most frequently encountered whiptail species in the trade, and for good reason. It's a manageable, rewarding fish for anyone curious about loricariids. Native to Venezuela, it has the characteristic elongated, flattened body of its family, well-suited to resting along substrate and driftwood while it grazes. Despite being listed as aggressive in some references, the practical experience of most keepers tells a different story: this is actually a peaceable species that does well in a quiet community. The catch is that it genuinely needs calm tankmates, as boisterous or competitive fish will push it out of the way at feeding time and cause it to withdraw. A small group of six or so, kept with gentle characins, Apistogramma, or Corydoras, suits it well. One genuinely interesting aspect of the genus is the ability to breathe air facultatively. A useful adaptation in the warm, sometimes oxygen-poor waters of its native range. Breeding is where this species really earns its reputation. Males are devoted guarders, selecting and cleaning a cave before tending eggs through to hatching with little help from the female. The fry require some patience to raise successfully, particularly around consistent food access and water quality, but this is a great entry point into catfish breeding.
