Green Tiger Loach - Syncrossus Hymenophysa : Complete Fish Profile & Care Guide

Table of contents


The Green Tiger Loach (Syncrossus Hymenophysa) is a fascinating and dynamic species that requires careful consideration when selecting tankmates due to its playful and sometimes aggressive nature. To ensure a harmonious community, it is best to house them with robust and fast-swimming fish, avoiding slow-moving, long-finned species that may fall victim to their nipping behaviour. These loaches are sociable creatures and thrive in groups of 5 or 6, with ten or more being preferable. When kept alone or in small numbers, they can become aggressive or withdrawn towards similarly-shaped fish. In such cases, the dominant individual may attack the others frequently, preventing them from feeding. For successful Green Tiger Loach (Syncrossus Hymenophysa) keeping, a mature aquarium with ample space, hiding places, and visual barriers should be provided. Smooth rounded rocks, driftwood, cobbles, and pebbles of varying sizes should be used to create a natural-looking environment that can support these active fish. It is crucial to use a substrate that has no sharp edges since these loaches tend to forage on the bottom of the aquarium, and their delicate sensory barbels can be damaged. Dim lighting is preferred, and the aquarium must be securely covered since these loaches are skilled jumpers who can escape through even the smallest openings. Robust filtration and good oxygenation are critical, as is a regular schedule of partial water changes. These loaches are intolerant of organic pollutants, and thus, partial water changes should be done regularly. The Green Tiger Loach's browny-tan body is adorned with 12-15 vertical bars featuring iridescent greenish-blue borders that begin at the dorsal surface and end towards the front of the fish, with a dark blotch on their dorsal fin. This unique colouration makes them a popular choice for aquarists seeking a visually striking addition to their aquarium.

How to breed the Green Tiger Loach

Regrettably, there is currently no available documentation of successful breeding of the Green Tiger Loach in captivity. Given that these loaches are migratory spawners in the wild, it is likely that their reproductive behavior is closely tied to seasonal cues and environmental conditions that are difficult to replicate in a home aquarium. As such, their breeding habits and requirements remain to be fully understood.

Diet & feeding

The feeding habits of the Green Tiger Loach are not too demanding, as they can consume a wide range of foods. It is important to provide them with a balanced and diverse diet consisting of high-quality dried products like flakes, granules, and sinking pellets. Additionally, they should be offered live and frozen foods such as artemia, bloodworms, and brine shrimp, as well as mosquito larvae and tubifex, which are particularly appealing to them. Fresh vegetables and fruits should also be included in their diet, such as blanched spinach, cucumber, courgette, and melon. Providing a variety of foods will help ensure the loaches receive all the necessary nutrients for optimal health and growth.
