Horadandia atukorali
Tiny Glowlight Carplet (Horadandia atukorali) for mature planted nano aquariums; peaceful, delicate and best kept in a calm group.
Glowlight Carplet (Horadandia atukorali), also known simply as Horadandia or Green Carplet, is a tiny Sri Lankan cyprinid for aquarists who enjoy subtle, natural movement rather than a large show fish. It is a small danio/rasbora relative with a slim body, clear fins, soft gold-green colour and a fine dark midline. In a planted aquarium it gives a delicate shimmer through the midwater without overpowering the aquascape.
This listing is for Petra SKU 4448, supplied as small juveniles around 1-1.5 cm. The species stays genuinely tiny, so it should be planned as a nano shoaling fish rather than a general community filler. It works best when the aquarium is mature, calm and planted, with enough of its own kind for confidence and enough small foods for every fish to feed before faster tank mates clear the water column.

The attraction of Horadandia atukorali is its delicacy. The fish is not built for a loud colour display; it is a refined, close-view species that rewards a planted layout and patient observation. Under gentle lighting the body can show a translucent yellow-green cast, and the line along the flank gives the fish its glowlight-style name.
Because the adult size is so small, the display depends on group behaviour. A single fish will look lost, while a group can create a fine, coordinated midwater layer above moss, Cryptocoryne, stem plants, leaf litter or a dark substrate. Use uncluttered front swimming space with cover nearby rather than a bare tank.
FishBase records this species from Sri Lanka, including still or slow-moving waters, swamps, rice fields, weedy coastal ponds, less saline mangrove swamps and less polluted canals. That points to calm planted margins, not fast current or exposed open water. A mature aquarium with stable filtration, gentle movement, floating plants and fine-leaved cover will make far more sense than a new bright tank with strong flow.
Use a dark substrate if possible, keep maintenance steady and avoid large sudden water-chemistry changes. A small planted tank can work well when it is mature and not overstocked, but a larger planted community gives more stable water and more room for a natural group. Protect filter intakes, especially with very small juveniles, and leave shaded areas where the group can settle after delivery.
Glowlight Carplets are peaceful, but their size makes them vulnerable. Avoid boisterous barbs, large tetras, cichlids, large gouramis, predatory catfish and any fish big enough to swallow a 1-3 cm carplet. Better companions are other tiny, calm species such as small rasboras, micro danios, peaceful dwarf shrimp colonies, pygmy Corydoras in suitable water and gentle Otocinclus-type algae grazers in established aquariums.
They should not be used as dither fish for territorial species. Keep them as a proper group so they can feed confidently, orient to each other and show natural movement. If they hide constantly, the usual causes are too few fish, bright bare surroundings, strong flow, large tank mates or food that is too big.
The mouth is small, so food size matters. Offer fine crushed flake, micro granules, powdered fry food, small frozen cyclops, baby brine shrimp, daphnia and other suitably tiny foods. FishBase notes insect feeding in nature, while aquarium trade sources describe a practical diet based on small frozen and dry foods. The goal is variety in portions small enough for every fish to take.
Several light feeds are better than a heavy single feed. In a planted nano aquarium, overfeeding can spoil water quickly, so watch body condition and remove uneaten food. If kept with faster fish, feed in more than one area or use foods that remain suspended long enough for the carplets to find them.
This is a small fish from quiet vegetated habitats, so clean stable water is more important than constant adjustment. Use a mature filter, keep nitrate under control, avoid sudden temperature drops and make water changes gently. If using botanicals or leaf litter, replace them gradually and keep oxygen levels healthy, especially in warm weather.
FishBase lists freshwater and brackish occurrence for the species, but ordinary freshwater aquarium care is the right approach for most keepers. Do not add salt casually to a planted community unless every inhabitant is known to tolerate it. Stability and compatible tank mates will do more for long-term success than chasing unusual conditions.
Acclimation should be calm and unhurried. Dim the lights, float the bag, mix water gradually and release the group near cover rather than into bright open water. Avoid heavy feeding on arrival day, then start with tiny portions once the fish are oriented and schooling. Over the first week, check that they hold position, breathe normally, feed confidently and keep a relaxed group pattern.
Because the fish are tiny, stress can show as hiding, clamped fins, poor feeding or separation from the group. Respond by checking temperature, ammonia/nitrite, flow, tank mates and food size before adding treatments. A stable planted aquarium is usually the best medicine.
Choose this fish if you want a refined planted-aquarium species with real nano character. It is a strong match for aquascapers, keepers of small peaceful communities and anyone who enjoys natural schooling behaviour over bold colour blocks. It is not the right choice for a rough community tank, a new uncycled setup, a large aggressive display or an aquarium where food competition is intense.
