Spotted Coolie Loach

A slim eel-like loach with a brown to orange body broken by dark spots, saddles, or irregular short bands.

Often hidden by day; a group and fine substrate encourage natural activity.

Mature females are generally larger and fuller through the abdomen. Males may show thicker or modified pectoral-fin rays, but the details vary by species and are not always visible in aquarium fish.

Provide an aquarium at least 90 cm long with a deep layer of fine, smooth sand for burrowing, rounded wood and stone, shaded cover, and no sharp gravel. Seal filter and lid gaps because loaches can enter narrow openings.

Spotted Coolie Loach is a substrate-oriented forager that probes sand and may bury most of its body when resting or alarmed. Activity increases in a secure group, during feeding, and under subdued light.

Maintain at least 5, preferably 8 where practical. A group encourages normal foraging without requiring constant close contact.

Generally non-territorial. Competition is more likely at feeding time than around fixed territories.

Peaceful community fish are suitable when they share the same temperature requirements. Avoid coarse substrate, aggressive bottom fish, and tankmates that consume all sinking food.

Maintain stable, clean water within the stated range. Oxygenation, low organic waste, and gradual acclimation are more important than forcing an exact pH or hardness value.

Provide small sinking foods after the fish are active. Use quality pellets or wafers with regular frozen or live invertebrates. Place some food near cover so shy or burrowing individuals are not outcompeted.

Do not assume these fish can live on leftovers. Confirm that food reaches them, especially in busy community aquariums.

An egg-scattering spawner with no parental care. Seasonal changes, abundant live food, and mature adults may trigger spawning among plants or over fine substrate. Protect eggs from adults and filtration, then begin the fry on microscopic foods.
