Green Tiger Loach

Overview

Green Tiger Loach (Syncrossus hymenophysa) is a bottom-dwelling fish for aquariums where the layout leaves enough open substrate area and the water stays stable.

Use these values as planning checks, then make sure the aquarium still has room for behavior, group needs, and calm community fish.

Care requirements

With a Intermediate care level, Green Tiger Loach is best for aquarists who can keep water quality steady and plan compatibility before adding the fish.

Because it uses the bottom area, leave enough open substrate area instead of crowding that part of the aquarium.

Plan the aquarium around the group, not just one individual.

With a lifespan of up to 8 years, this is a fish to plan for long term rather than an impulse addition.

Aquarium size and space needs

An aquarium of 300 L or larger can be a reasonable starting point, but it should not be read as permission to overstock.

At up to 25 cm, Green Tiger Loach stays small, but a group still needs room to move, feed, and avoid constant competition.

Uses the bottom area, so leave enough open substrate area for movement and feeding.

A group of 6 or more should have enough open substrate area for movement and feeding.

Water parameters

The temperature range for this fish is 25 to 30 °C, which fits many tropical freshwater aquariums. Choose other fish with overlapping temperature needs.

The pH range for this fish is 6 to 7.5. That points to slightly acidic to neutral water, but stability is more important than sudden corrections.

The GH range for this fish is 3 to 15 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.

Temperament and compatibility

Green Tiger Loach needs more careful companion choice because the temperament data suggests space, boundaries, or similar-sized fish may matter.

If kept in a group of 6 or more, the aquarium should have enough open substrate area for the group rather than being planned around a single fish.

Because this fish uses the bottom area, compatibility is easier when other fish are not all competing for the same swimming space.

Swimming zone and behavior

This fish uses the bottom area, so leave enough open substrate area for movement and feeding.

Because this species is best planned as a group of 6 or more, bottom space matters more than body size alone.

Feeding

As an omnivore, Green Tiger Loach should receive a varied diet rather than one repeated food type.

Because it feeds near the bottom, make sure food reaches the substrate and is not completely taken by faster fish in the open water.

Natural habitat and origin

This profile currently lists the origin as Indonesia Malaysia. Treat this as a broad regional note rather than a complete habitat description.

Before adding this fish

Use this checklist before treating the profile as a match for an existing aquarium.

• Plan for an aquarium of 300 L or larger.
• Make sure the bottom area has enough open substrate for a group.
• Choose other fish with overlapping temperature needs.
• Keep pH stable within the listed range instead of making sudden corrections.
• Choose other fish carefully around this temperament.
• Plan for a group of 6 or more.
• Offer a varied diet suitable for an omnivorous bottom-dwelling fish.
