Lake Inle Danio Care Guide - Aquarium Setup, Diet & Breeding

The Lake Inle Danio is a small, elegant cyprinid with a slender body and a lively, streamlined profile. Its colouring can show attractive golden, bronze and purplish tones, with iridescence that becomes especially noticeable as the fish turns in the light. Subtle darker markings along the body add to its refined appearance.

This is an active but generally peaceful shoaling fish. Groups move through the open water with quick, purposeful bursts, displaying most natural behaviour when kept alongside several of their own kind. Their small size and constant activity make them appealing inhabitants of a planted community aquarium.

In the wild, the species comes from the Lake Inle basin, a high-elevation freshwater environment known for extensive shallow areas, aquatic vegetation and floating gardens. The fish is adapted to clear, oxygenated water and habitats with plenty of cover as well as open swimming space.

Lake Inle Danios are less commonly encountered than many established danio species, and their restricted natural range makes responsible sourcing particularly important. Their understated colours and unusual origin give them special interest for aquarists who enjoy keeping less familiar Southeast Asian fishes.

Lake Inle Danios are endemic to Lake Inle and its surrounding waterways in Shan State, eastern Myanmar, in Southeast Asia. They are associated with the shallow, vegetated freshwater habitats of the lake basin.

A group should be given at least 60 litres, with a tank around 60 cm long or more to provide useful horizontal swimming space. Use gentle to moderate filtration with good oxygenation, open areas for shoaling and dense planting around the sides and rear for security. A dark, fine-grained substrate, smooth furnishings, floating plants and subdued areas of shade help the fish feel comfortable while allowing their colours to stand out. Keep the aquarium mature, stable and securely covered, as active danios may jump.

Up to about 4 cm (1.6 inches) in total length. Females are usually a little larger and deeper-bodied than males, while males tend to remain slimmer.

Offer a varied diet of suitably small foods, including quality micro-pellets or finely crushed flake, small frozen foods and occasional live foods such as baby brine shrimp, daphnia and mosquito larvae. Their small mouths favour frequent portions rather than large meals. Live and frozen foods are particularly useful for bringing out colour and conditioning adults for spawning.

Lake Inle Danios suit peaceful community aquariums containing similarly sized, non-aggressive fish. Suitable companions include small rasboras, other gentle danios, celestial pearl danios, small tetras, freshwater shrimp and peaceful small loaches or Corydoras, provided the aquarium is appropriately arranged. Avoid large or predatory fish, fin-nippers, boisterous species and tankmates that require substantially warmer water, as these may intimidate, injure or outcompete this delicate danio.

Lake Inle Danios are egg-scattering spawners that can breed in a mature aquarium when well conditioned with varied, protein-rich foods. Use a separate breeding tank with fine-leaved plants, spawning mops or a protective mesh layer so the adults cannot eat the eggs. Scatter spawning usually takes place among the plants, after which the adults should be removed. The eggs generally hatch within a few days, and the tiny fry can be raised on infusoria or other appropriately sized first foods before moving on to newly hatched brine shrimp.

Females are generally fuller through the belly, particularly when carrying eggs, and may be slightly larger overall. Males are typically slimmer and can show stronger golden or purplish colouration when displaying or courting.
