Water parameters
Overview
The eel loach is one of the slimmest and longest kuhli species; adults reach 10–12 cm. Its body is mostly plain gray or gray-brown; some populations show a thin lateral line or small dark spots. It has no nasal barbels. Because it is spread over a wide area, it is debated whether it is a single species or several very similar ones.
Tank Setup
- At least 60 liters for a group of 5–6.
- 23–28°C, pH 6–7.5, soft water.
- Fine, soft sand is essential; roots, leaves and narrow shelters.
- Gaps in the lid should be closed and a sponge fitted over the filter intake.
Diet
It searches the sand for small insect larvae and crustaceans. Offer sinking granules and tablets, frozen daphnia, brine shrimp and bloodworms.
Behavior and Compatibility
Extremely peaceful; it hides in narrow corners and in the sand all day and roams as a group in the evening. It may eat eggs and small fry.
Good companions: rasboras, tetras, dwarf gouramis, corydoras, other kuhlis, shrimp.
Avoid: large fish that could swallow it, cichlids that claim the bottom, aggressive botias.
