Chinese Fire Belly Newt
Cynops orientalis · also called Oriental fire-bellied newt, Fire belly newt, China newt, Dwarf fire belly newt, Hypselotriton orientalis
A small, hardy, semi-aquatic newt with a black body and a vivid orange-red belly; long-lived and popular, but cooler-water needs make it an intermediate pet.

Part of the Newts
Semi-aquatic salamanders kept in cool, clean, planted aquatic setups with land access. Many have toxic skin, so they are observation animals that require careful hand-washing and no casual handling. Many genera are now restricted in US trade under Lacey Act Bsal-fungus rules.
Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Habitat & enclosure
Chinese fire belly newts are semi-aquatic and spend most adult life in water, so they are kept in an aquarium rather than a dry terrarium: at least a 10-gallon (about 38-liter) tank for two or three newts, with shallow, gentle water (these are weak swimmers) and an easy-to-reach land area such as a cork bark island, floating ledge, or sloped gravel bank so they can rest out of water. A secure, tight lid is critical because newts climb and escape readily. Provide live or silk plants, hides, and gentle, well-filtered, fully cycled water.
This is a cool-water species and one of the main care challenges: water should be kept around 60-68 F (16-20 C) and ideally not above the low 70s F, so most homes need no heater and may even need a fan or chiller in summer. Use dechlorinated water with a near-neutral pH, perform regular partial water changes, and keep ammonia and nitrite at zero. Subdued lighting suits them.
Substrate
For their largely aquatic setup, use large smooth river stones or bare bottom—anything small enough to swallow risks fatal impaction. Provide a cork-bark or floating-plant land area for resting, with no sharp or ingestible gravel.
Equipment & setup
A cool aquatic tank (kept 60-68F, never above ~72F—a chiller or fan may be needed) with gentle filtration and low flow, a tight escape-proof lid, and easy land access. No heat lamp is needed; provide hides and live or silk plants, and dim, indirect lighting.
Diet
Fire belly newts are carnivores fed small meaty invertebrate foods such as frozen-thawed bloodworms, blackworms, brine shrimp, daphnia, chopped earthworm, and small portions of newt or carnivore pellets where accepted. Many are reluctant to take dry food, so frozen and live foods make up the bulk of the diet. Feed near the newts since they are slow, deliberate hunters.
Feed adults every two to three days and juveniles more often, removing uneaten food to protect water quality. Avoid overfeeding, which fouls the water and can cause obesity. Because they take food in water, target feeding with tongs or a turkey baster helps ensure each animal eats.
Behavior & temperament
These newts are slow, peaceful, and active across day and night, often seen walking along the bottom or surfacing for air. They are social and do well in small groups of similarly sized individuals, but they should not be handled routinely: like all fire-bellied newts they secrete tetrodotoxin-related skin toxins that are dangerous if ingested or rubbed into eyes or broken skin, so always wash hands thoroughly after any contact and never house them where the toxin could reach a vulnerable tankmate.
Their bright orange belly is an aposematic (warning) signal, sometimes shown in a defensive arched posture. Enrichment comes from planted cover, varied hiding spots, gentle water flow, and live or moving foods that engage their hunting behavior.
Health
The most frequent health problems trace to water that is too warm or of poor quality, leading to stress, fungal and bacterial skin infections, and bloat; heat stress in particular is a common killer of this cool-water species. Many imported newts also arrive with internal parasites or in poor condition, and chytrid is a concern.
Prevention means keeping water cool and clean, fully cycling the tank, doing regular dechlorinated water changes, providing reliable land access, and quarantining new animals. Watch for skin fungus, sores, bloating, floating problems, or appetite loss and consult an amphibian-experienced veterinarian. Note the toxic skin secretions when keeping this species around children or other pets. This entry is educational and not a substitute for veterinary care.
Tips, DIY & hacks
These newts secrete toxins, so wash hands before and after handling and minimize handling. Feed bloodworms, blackworms, and small earthworms via tongs; keep water pristine with regular changes, quarantine new arrivals, and never house with fish that nip or compete.
