Species description
Geographical Origin and Habitat: This critically endangered newt is endemic to the Zagros Mountains, occurring in pristine, cold-water mountain streams along the border region between Iran and Iraq. They inhabit highly oxygenated, glacier-fed streams at high elevations, sheltering under rocks to avoid the intense sun of the region.
Taxonomy and Genetics: The Kurdistan newt features a striking, toxic-avoidance coloration. Its smooth, rubbery skin is pitch-black, densely covered with tiny, circular yellow or orange spots (hence the name *microspilotus*). The belly is a solid, vibrant orange. Adults typically measure between 14 and 18 cm in length, possessing a flattened tail designed for swimming.
Behavior and Habits: Primarily aquatic during the breeding season, they spend late winter and spring in the cold, moving water of mountain streams. They are diurnal, active hunters that forage among submerged rocks. During the dry season, or if streams dry up, they estivate under rocks or in damp terrestrial crevices.
Morphology: During the breeding season, males develop a swollen cloaca and a slightly broader, more flattened tail with a whitish sheen to attract females. Females are generally larger, heavier, and have a more rounded, robust body shape.
Care, breeding and tankmates
Terrarium Setup: Requires a semi-aquatic setup (paludarium) or a specialized aquarium (at least 80x45x45 cm). The aquatic zone should make up 70% of the enclosure with a water depth of 15-20 cm, equipped with a powerful water pump to simulate rapid stream currents. The remaining 30% should be a damp terrestrial area with flat rocks or cork bark for land access.
Lighting and Heating: Extremely sensitive to heat; cool temperatures are vital. Water temperature must be kept between 14-18°C. A water chiller is highly recommended, as temperatures above 22°C can be fatal. A winter cooling period (4-8°C) is required for long-term health. Low-output 5% UVB lighting should be provided.
Humidity and Hydration: In the terrestrial zone, maintain high humidity (80-100%) with excellent ventilation to prevent mold and bacterial skin infections. Water quality must be pristine, using a robust biological filter and regular partial water changes with declorinated water.
Feeding and Supplementation: Strictly carnivorous. Feed a diet of bloodworms, blackworms, chopped earthworms, daphnia, and small snails. They are slow feeders, hunting by sight and smell. Dust terrestrial food items with calcium and multivitamin supplements occasionally.
Compatibility: Generally peaceful and social when housed in small groups of their own species. Do not house them with other species to prevent disease transmission and hybridization. Ensure adequate hiding places for all individuals.
Health and Common Diseases: Extremely vulnerable to heat stress and poor water quality, which can cause skin lesions, fungal infections, and bacterial septicemia. Handling should be avoided; if necessary, use wet gloves, as the natural oils and warmth of human hands can burn and damage their skin.
