Whiptail Catfish

About

Found in the upper Amazon basin, this slender loricariid, Rineloricaria lanceolata, is one of the species most commonly sold under the name whiptail catfish. And for good reason. It has a characteristically elongated, lance-shaped body with armored plating and a long tapering tail, giving it that unmistakable whiptail silhouette. Despite the "aggressive" flag that occasionally gets attached to this species, that really only applies during spawning; day to day, it is one of the more laid-back catfish you can keep. It does best alongside small, calm fish, think small characins, Apistogramma, or Corydoras, and will become withdrawn if housed with boisterous or competitive tankmates that outcompete it for food. Keeping a small group is recommended, both for the fish's well-being and to increase the odds of obtaining a compatible pair. Breeding is genuinely achievable for intermediate keepers who put in the prep work. Males select and clean a cave, a short length of PVC pipe works perfectly, and take on sole responsibility for guarding and fanning the eggs after spawning. The fry are manageable but need constant access to soft vegetable matter and clean water to thrive. Like others in its genus, it can breathe air facultatively, which hints at its adaptability in the wild.
