Kuhli Loach: The Fish That Looks Like a Tiny Eel

In this guide

Overview

The kuhli loach has a long, slender, eel-like body banded in orange-brown and black, and spends most of its time burrowing through substrate or hiding in cover rather than swimming in open water. It comes from Southeast Asia and reaches around eight to eleven centimetres.

Its secretive, nocturnal nature means many owners rarely see their kuhli loaches during the day, which can make a new keeper wonder if the fish is even still alive, when in fact it is simply doing exactly what this species does naturally.

Tank and water requirements

A group of six or more does well in a tank of sixty litres or more, with a soft, fine substrate that lets them burrow without injury, along with plenty of hiding spots such as caves, plants or driftwood. A secure lid matters more with this species than with almost any other on this list, since kuhli loaches are notorious escape artists capable of squeezing through remarkably small gaps.

They tolerate a range of water conditions, including typical Indian tap water, and appreciate dim lighting that better matches their naturally nocturnal habits.

Diet and behaviour

Sinking pellets, wafers and occasional live or frozen food suit their bottom-feeding, scavenging habits well. They are entirely peaceful, and their shy, burrowing nature means they rarely interact much with other tankmates beyond their own kind.

Feeding after lights out, or using a feeding tube to get food directly to the substrate, helps ensure this naturally hidden fish is actually getting enough to eat in a busy community tank.

Buying tips

• Priced around thirty to seventy rupees per fish in most Indian shops
• Check the tank lid and any filter intake gaps carefully before buying, since kuhli loaches are genuinely skilled escape artists
• Keep in a proper group rather than alone, since they are more confident and visible when kept socially
