Eastern newt

Notophthalmus viridescens can have aquatic larvae, terrestrial efts and aquatic adults. Some forms skip or modify stages; the illustration depicts an adult.

Confirm regional form and current life stage.

Confirm the actual life stage and captive-bred source before deciding whether an aquarium is appropriate.

Arrange dependable holiday care and keep money available for food, replacement equipment and appropriate veterinary help. Test the habitat before the animal arrives.

For aquatic adults, Wildform proposes at least a 60 × 40 cm footprint with still-water planting and an accessible land rest. Efts need a secure damp woodland terrarium instead; an aquarium is not their default housing.

Measure usable internal space after substrate, guards and furnishings. Check ventilation, cable holes and access against the smallest occupant. Fix heavy furnishings independently of loose substrate.

Aquarium-only housing is not suitable for every life stage.

The keeper account describes 18–23°C for active adults and a separate colder winter regime. Winter cooling is not prescribed here for new, juvenile or unassessed animals.

Record the warm and cool locations, overnight minimum and daytime maximum. Air, surface and substrate readings are different measurements. Any added heater needs compatible thermostatic control and safe separation from the animal; assess summer cooling as well as winter heating.

Provide gentle day/night lighting with substantial shade and concealment. Prevent lamps warming the water.

Keep the night dark and provide retreat from daytime light. Lamp percentage, electrical wattage and a product name cannot establish the exposure reaching an animal. Check the finished installation after changes to mesh, branches or lamp position.

Aquatic adults need cycled, clean low-current water; efts need moist terrestrial refuges with ventilation. Both need secure lids and life-stage-safe exits.

Inspect the occupied refuge and substrate as well as the air reading. Adjust water provision and ventilation together, and clean contaminated drinking surfaces. A single humidity number cannot describe every microclimate.

Use suitable small worms and other assessed invertebrates. Terrestrial efts need prey presented for terrestrial feeding; do not assume an adult pellet diet transfers.

Record what is actually eaten and follow changes in growth and body condition. Food size, life stage and the full diet matter. Supplement products require an individual plan; do not combine calcium, vitamin D and multivitamins by guesswork.

Check the animal’s individual feeding needs.

Avoid handling and mixed-species housing. An adult repeatedly leaving water may signal a habitat or health problem rather than misbehaviour.

Make necessary maintenance predictable and allow voluntary retreat. Prepare a secure transfer container before essential moves. Observation should not repeatedly interrupt feeding, rest or moulting.

Record weight/condition, skin and appetite and check water quality when behaviour changes.

Keep dated observations of appetite, activity and condition. A sudden decline, injury, abnormal breathing or repeated failed moults needs appropriate professional assessment. This guide does not provide a diagnosis or medicine dose.

Agree the individual seasonal regime.

Retain species, form, stage and disease/source records and check current Caudata import conditions.

Ask for a dated source record, scientific identity, life stage and established care history. Keep new arrivals and their equipment separate while an appropriate quarantine plan is agreed. Check current official rules for the exact animal, route and transaction before importing or buying; this page does not establish legal clearance. Never release animals or viable eggs outdoors.

Check the correct life-stage habitat, temperature and actual food intake. Review developmental changes and maintain separate terrestrial/aquatic equipment as needed. Keep a dated record of measurements and observations, and revisit the full advice when conditions or life stage change.
