🦎 How to Set Up a Newt Tank (Cool Water, Land and Water)
Newts are watch-do-not-hold amphibians that live in a semi-aquatic tank — part water to swim in, part land to rest on. A 10 to 20 gallon long tank suits most beginner newts, with a sloped shore or floating platform so they can climb out.
Cool is the rule. Newts need cool water (room temperature or below) and should never have a tropical heater — a warm tank is the most common cause of newt illness. A thermometer helps you catch a too-warm room.
Add a tight lid — newts are surprising climbers and escape through any gap — plus a gentle sponge filter and hides. Their skin absorbs everything, so keep hands out and the water clean. For species picks, see our best newts for teens guide.

🧽 Cleaning & maintenance
The main job is regular water changes. Each week, use a gravel vacuum (siphon) to remove about 20–30% of the water along with waste from the bottom, then refill with fresh water treated with a dechlorinator so it is safe. Scrape algae off the glass as needed and rinse the filter media in old tank water — never tap water, which kills the good bacteria. Test the water so you can catch problems early. Never do a full strip-down that wipes out the filter bacteria; steady partial maintenance keeps the water stable and your newt healthy.
