Frog heat mat and thermostat placement — never underneath Diagram of a frog terrarium with a heat mat on the outside back or side connected to a thermostat. The probe hangs inside the tank next to the heat mat to monitor warm-end temperature. Never place a heat source under the enclosure because frogs move down to avoid heat and will keep getting warmer. Set day and night temperatures from the popular species guide, overall about 60 to 84 degrees Fahrenheit.

02 · Climate

Temperature, humidity & water

Side or back heat only, species day/night bands, heavy morning spray, and clean dechlorinated soak water every day.

Temperature — use your species’ day / night pair

Most species need supplementary heating unless the room is consistently warm. Across popular forms, daytime targets span roughly 76–84 °F (24–29 °C) with nights about 60–70 °F (16–21 °C) — set the band for your species in the guide below. Temperate forms need slightly lower warm-end temperatures.

  • Preferred: heat mat outside back or side + thermostat
  • Examples: White’s / RETF ~84 day · Bird Poo Mossy ~76 / 60 · many ground forms ~78–82 / 68–70
  • Never under the tank

03 · Nutrition

Diet & feeding

Small amounts of live insects, trial-and-error portion sizes, and 4:1 calcium to Nutrobal on every feed.

At a glance

Feeding cheat sheet

Prey
Live insects sized to the frog (e.g. crickets)
Young
About 3–4 times per week · start with a few in the evening
Adults
Appetite often lessens with age — most eat only a small amount
Dust
4 parts calcium (+ Mg) : 1 part Nutrobal every feed
Gut load
Varied commercial insect foods + safe fresh vegetables for feeders

Portion trial

First days

  • Offer a few crickets in the evening
  • If gone by morning, increase the amount
  • Within days you will know daily intake

Supplements

Every feed

  • 4:1 calcium (+ magnesium) to Nutrobal
  • Coat insects every time you feed
  • Gut-load feeders — not carrot alone
Gut loading deep dive Why feeder diet quality matters

Most people underestimate gut loading. In the wild, amphibians take a wide variety of prey that already carry a full nutrient profile. Buying a tub of crickets and tossing them in with only a piece of carrot or potato leaves an incorrect calcium-to-phosphorus ratio and a thin vitamin base.

The broader the range of food you feed the insects — commercial gut-load diets plus safe fresh vegetables suitable for reptiles — the healthier your frog will be.

04 · Behaviour

Handling & behaviour

Most frogs prefer not to be handled — wet hands only if you do, and White’s tree frogs tolerate it best.

  1. Preference

    Most dislike handling

    A few tolerate it better than others. White’s tree frogs are the best choice if you want a frog that is less likely to jump away and stress.

  2. Skin

    Wet hands only

    Always wet your hands before and throughout handling — dry hands can damage the frog’s skin.

  3. Note

    They can spray

    Frogs can spray urine for some distance when handled.

  4. Warning

    Hygiene & air quality

    Wash hands before and after. No aerosols or plug-in air fresheners near the enclosure.

05 · Welfare

Health & welfare

Correct side heat, humidity without flooding, clean water, and careful dusting keep amphibians healthy with a simple daily routine.

Best prevention: good husbandry

Size the tank from the species table, run a heat mat on the outside back or side only, spray heavily in the morning, change water daily with treated water, dust insects 4:1 every feed, and clean tree-frog setups about every six weeks (ground forms about four).

Questions

FAQ

What size enclosure does a frog need?

Match the tank to the form you keep using the popular species guide. Many tree frogs (White’s, Red Eyed, Amazon Milk, Bird Poo Mossy, American and European Green) use a minimum adult tank of 45 × 45 × 60 cm (~18 × 18 × 24″) with more height than ground. Fire-bellied toads, dart frogs and golden mantellas often use 45 × 45 × 45 cm; horned frogs 60 × 45 × 45 cm; Giant African Bullfrog 90 × 45 × 45 cm. Asian Giant River Toad size is confirmed with our team when you buy. Glass or plastic/PVC is fine if well ventilated. Arboreal forms need height; terrestrial forms need floor area.

How do I heat a frog setup?

Most species need a heat mat unless the room is consistently warm. Place the mat on the outside of the tank along the back or side only, on a thermostat with the probe hanging inside by the mat to monitor the warm end. Never put heat under the enclosure — frogs move down to avoid heat and will keep getting warmer. Set day and night from the species table (overall about 60–84 °F / 16–29 °C depending on form). Temperate species need slightly lower warm-end temperatures.

What humidity and water do frogs need?

Most commonly kept forms come from tropical humid habitats. Give a heavy morning spray and an extra evening spray if ventilation is high; misting or fogging systems help, but it is better to under-mist and top up by hand than waterlog the tank. Humidity bands in the species guide range from about 50–70% (European Green Tree Frog) up to 70–100% (dart frogs, mantellas, mossy frogs). Change the water dish daily — frogs bathe and absorb water through the skin. Use only dechlorinated water (Reptisafe, bottled, or water stood 24 hours).

What do frogs eat?

Live insects sized to the frog. Offer a few crickets in the evening when you first get them and adjust — most eat only a small amount. Youngsters often 3–4 times per week, then less often as appetite drops with age. Dust every feed with a mix of 4 parts calcium (+ magnesium) to 1 part Nutrobal multivitamin. Gut-load feeders on a varied diet so calcium-to-phosphorus and vitamins are adequate.

Can I handle my frog?

Most frogs do not like handling. White’s tree frogs tolerate it better than most and are less likely to jump away. If you handle, wet your hands before and throughout — dry hands can damage the skin. Frogs can spray urine some distance. Always wash hands before and after, and never use aerosols or plug-in air fresheners near the enclosure.

How often should I clean a frog enclosure?

Tree frogs often need a full clean about every six weeks because they may defecate on the glass, leaving substrate and foliage relatively clean. Ground-dwelling frogs need cleaning around every four weeks. Spot care and daily water changes keep the setup healthy between full cleans.
