Spined Loach - Cobitis taenia : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Spined Loach (Cobitis taenia) is a fascinating and peaceful, mostly solitary and nocturnal species. During the day, these fish tend to bury themselves in the substrate, with only their head and tail visible. However, at night, they emerge to sift through the substrate using their mouth and gills to forage for food. While not recommended for beginner aquarists, the Spined Loach is a remarkable species to keep for those willing to meet their specific requirements. Unfortunately, the fish's temperature needs can be a significant obstacle to maintaining them in domestic aquaria. As they come from regions that experience extremely cold winters, their water must be much colder than typical central-heated domestic settings can provide. The Spined Loach boasts an elongated, flat-sided body ranging from brownish-grey to yellow. Dark brown patches decorate their flanks, forming a broken band down their upper and lower sides. The fish's stomach has a whiteish-yellow colouration, and they possess six barbels around its mouth, which can be challenging to see. Additionally, they sport erectile spines below their eyes, which gives them their common name. Overall, the Spined Loach is a captivating species that can add interest and intrigue to any aquarium. With their unique characteristics and specific needs, these fish are an excellent choice for those seeking a challenge and a rewarding experience.Spined Loach Photos
Sexual Dimorphism
Distinguishing between male and female Spined Loaches can be a relatively demanding task. Typically, males exhibit a more extended and thicker second ray on their pectoral fins, accompanied by an enlarged scale at its base. Conversely, females tend to be larger than their male counterparts.Quick Facts
