Pike Characin

About

The pike characin (Boulengerella cuvieri) is a torpedo-shaped predator from the fast-moving rivers and streams of the Amazon, Orinoco, Tocantins, and several other South American drainages. It belongs to the family Ctenolucidae, a small but distinctive group of characins recognizable by their needle-like jaws, tapering body, and rows of small, curved teeth built for gripping prey. In the wild, adults favor surface zones behind rocks and submerged logs in swift current, though younger fish sometimes turn up in quieter bays and backwaters. This species is a dedicated fish-eater and will treat anything it can fit in its mouth as a meal. That said, it is generally tolerant of larger tankmates. Good candidates include big cichlids like Cichla and hefty doradid or loricariid catfishes. Juveniles show a clear schooling tendency and should be kept in groups of four or more; adults become more solitary but still benefit from company. Be honest with yourself about the size commitment here. Adults routinely reach two feet or more, and responsible sources note that only a small number of private keepers have tanks large enough to house this fish properly for its full life. Breeding in captivity has not been documented.
