Dario Hysginon Care Guide: Flame Red Dwarf Badis
Vivid flame-red colouration packed into a body barely 2 cm long makes Dario hysginon one of the most striking nano fish available to hobbyists. This Dario hysginon care guide from Gensou Aquascaping at 5 Everton Park, Singapore covers the specific requirements of this dwarf badis, a fish that rewards patient keepers with remarkable colour and fascinating territorial displays.
Species Profile
Dario hysginon belongs to the family Badidae and originates from shallow streams in northern Myanmar. Males display an intense orange-red body with subtle barring, while females are a dull grey-brown and considerably smaller. Maximum size is around 2 cm for males and 1.5 cm for females. They are shy, slow-moving predators that spend most of their time lurking among plants and leaf litter.
Tank Size and Aquascape
A single male can be kept in as little as 15 litres, but a 30-litre tank suits a trio of one male and two females more comfortably. Dense planting is essential. Use fine-leaved stems like Rotala, mosses and floating plants to create multiple territories and sight breaks. Leaf litter on the substrate mimics their natural habitat and encourages foraging. Keep lighting moderate; harsh overhead light washes out their colour.
Water Parameters
Aim for pH 6.5 to 7.5, GH 2-10 and temperature 20 to 26 degrees C. Singapore’s soft tap water after dechlorination sits within this range without much adjustment. In the local climate, ambient room temperature is often at the upper end of their comfort zone. A small clip-on fan can help if temperatures regularly exceed 28 degrees C during the hotter months.
Feeding: The Live Food Challenge
Here is where many hobbyists struggle. Dario hysginon are reluctant to accept dry foods. Live or frozen foods form the backbone of their diet. Daphnia, baby brine shrimp, grindal worms and micro worms are all eagerly taken. Frozen bloodworms (chopped small) work as a convenient alternative. Feed small amounts twice daily. Some keepers report success training them onto crushed pellets over weeks, but do not rely on this.
Culturing live food at home is practically a necessity for long-term success. A simple daphnia or micro worm culture costs almost nothing to maintain and ensures a steady supply.
Behaviour and Tankmates
Males are territorial towards each other. In a 30-litre tank, keep only one male unless the tank is heavily planted with at least three distinct territories. Females are tolerated but may be chased during spawning attempts. Suitable tankmates include very small, peaceful species: Boraras brigittae, pygmy corydoras (Corydoras pygmaeus) and small shrimp like cherry shrimp. Avoid anything boisterous or large enough to intimidate them into hiding permanently.
Breeding
Spawning occurs among fine-leaved plants or moss clumps. The male entices the female into his territory with fin displays and intensified colour. Eggs are tiny and adhesive, laid in batches of 10 to 30. The male guards the spawn loosely but may eat eggs if disturbed. Removing the female after spawning improves hatch rates. Eggs hatch in two to three days at 25 degrees C. Fry are extremely small and require infusoria or Paramecium for the first week.
Health and Common Issues
Starvation is the primary killer. Fish that refuse frozen food and do not receive live food will waste away within weeks. Watch for a concave belly, a clear sign of underfeeding. Parasitic infections can occur in wild-caught specimens; a two-week quarantine with observation is advisable. Maintain excellent water quality with weekly 20-percent changes and avoid overstocking.
Sourcing in Singapore
Availability is sporadic. Check specialist shops around Serangoon North Avenue 1 and hobbyist sellers on Carousell. Prices range from $4 to $8 per fish. Buy at least a trio if possible, as solitary individuals often hide and never show their best colour. Locally bred specimens, when available, tend to adapt better to prepared foods than wild-caught imports.
