Making height usable

Secure horizontal, sloping and vertical branches to the structure, using diameters that offer grip and supports suitable for adult weight. Connect them from the exposed lighting branch to the cool area, distributing supports across levels. Place hide entrances beside branches; add foliage along routes without blocking dishes, doors or vents.

Testing and access

Connect specified heat sources to compatible thermostats and guard against contact. Secure probes according to device instructions; measure air at resting sites and heated surfaces separately with independent instruments. In housing with water, also check water temperature and quality: one zone’s thermostat does not control the others.

With the complete enclosure running, record day and night readings and compare them with the sheet. Test doors, cable openings and cleaning access, keeping vents clear. Change one variable at a time and recheck after each adjustment.

Light in the animal’s daily life

Sleeping leaves must provide actual shade. Maintain a screened route between resting sites and water and check back height at the highest accessible point.

An example layout in the enclosure

To make the layout concrete, take housing measuring 46 × 46 × 61 cm, using the first dimensional configuration in the sheet. This is a mounting example: retain the conditions and any alternatives attached to the stated minimum.

In a wooden enclosure with internal lighting, imagine the tube 56 cm above the floor and the back or head at 25 cm. The geometric distance is therefore 31 cm. The branch or platform lies below animal height, according to body size. Place lighting over one side, with a route to fully screened retreats.

In a glass enclosure with a mesh roof, retain the same animal height and imagine the tube 5 cm above the mesh: distance becomes 41 cm. Mesh attenuates UV variably; ordinary glass roofs block UVB. Increasing the percentage alone is insufficient: measure beneath the mesh and adjust height, output or layout as needed.

These distances describe the example, not a safe clearance for every lamp. Select the source and adjust mounting until approximately UVI 1–2 is measured at animal height in the exposed position. Also respect the minimum clearance specified for the model used. Recheck with furnishings, guards and mesh installed, including the highest reachable points and animal growth.

Choosing and checking lighting

First define the patch that should illuminate the whole body and the route to a screened retreat. For a broad patch, select a linear tube with reflector; consider a compact only if its useful patch covers the body and leaves an accessible gradient. Check model, output, reflector and mounting distance, then compare measured UVI with the species target. Label UVB percentage alone cannot determine distance and intensity.

The decisive check uses a UVI metre facing the source at animal height. Check the centre and edges of the exposed patch, the highest supports and retreats, which must allow withdrawal from UV. Repeat after moving equipment, changing lamps and plant growth. Without a metre, use the manufacturer’s instructions and measurements for the exact configuration, including safety clearances.

When UVB or UVA are absent

When keeping without UVB, D3 must be supplied through a complete diet or species-appropriate supplementation. Calcium alone does not replace D3. Check existing amounts in prepared diets and multivitamins before combining products; dosage also depends on diet and cannot be derived from lighting hours.

UVA has no dietary replacement. Maintain appropriate illumination and photoperiod without adding an intense source to compensate for unverified information: amphibian exposure must be evaluated by species and life stage.

Sex, maturity and readiness

Select identified adults of the same species with stable weight; size and calling help distinguish sexes but cannot establish age. Record origin and prepare rearing housing with plentiful supports for small arboreal frogs.

Start a record for each breeding animal with identity, origin, documented age and previous weights. Compare the weight trend with growth and body condition; delay introductions for animals still growing rapidly, losing weight or recently acquired. Use stated ages as guidance alongside these checks. If sex cannot be identified reliably, obtain assessment by qualified personnel before pairing.

Preparation and seasonal cycle

Prepare the wet phase while retaining ventilation, dry resting areas and broad leaves over a water basin. Misting should wet the environment without turning the enclosure into stagnant water; test drainage before introductions.

Before encounters, prepare and test offspring enclosures and have first foods available. Check records for regular adult feeding and good body condition, then verify access from exposed areas to retreats. If the species protocol includes seasonal changes, adjust settings gradually and record the response. Record night-time air, surface and egg temperatures separately, noting where each is measured. Keep water available throughout preparation.

Courtship and mating

The male calls and remains clasped to the female. Provide sturdy routes between supports, water and laying leaves that can carry the pair. Observe at night with minimal disturbance and record the selected site.

Spawning and egg collection

Eggs are laid on leaves above water: do not submerge them like other frog eggs. Keep the leaf and jelly hydrated, with clean water below to catch tadpoles dropping at hatching; preserve orientation and support if moving the leaf.

Aquatic development and hatching

Dehydration can trigger earlier hatching and reduce survival: earlier emergence is not a benefit to pursue. Check jelly, mould and access to the basin below daily. Early hatching calls for particular attention when establishing larvae.

Use water treated for chlorine and chloramine at the same temperature as the original container. Guard intakes and keep movement gentle. Check eggs and water daily, remove dead material without breaking healthy eggs, siphon leftovers and faeces, test ammonia and nitrite and change water with prepared water as needed.

First meals and juvenile care

Start tadpoles on fine omnivorous tadpole food and monitor consumption and water quality. Prepare a ramp and low leaves before forelimbs appear; emerging froglets must reach land without prolonged swimming. Offer microfeeders when hunting begins.

Observe each larva’s feeding, growth and developmental stage daily, avoiding unnecessary capture for weighing. Also check water quality, injuries and size differences: a feeding group does not establish that every larva eats. Separate injured individuals or those excluded from food, and adjust space and diet as they develop. For forms that become terrestrial, prepare gentle exits and shelters before the transition to land.

Female recovery

After reproduction provide water and the usual balanced diet, initially in manageable portions; monitor weight, activity and return of appetite. Keep supplements and lighting consistent with the feeding guide. Avoid further introductions until the previous condition has recovered; later clutches may occur without another mating. Persistent straining, weakness or protruding tissue require veterinary attention, without squeezing the abdomen.

Equipment and example diary

Prepare rearing tanks, covers, a mature sponge filter or containers for regular water changes, water tests, a narrow siphon, thermometer and productive first-food cultures. The number of offspring raised must match the actual capacity to feed them and maintain clean water.

A consistent diary using actual dates helps follow reproduction in Agalychnis callidryas. Start with adult identity, weight and condition, then record observed encounters, laying or birth and development conditions. After emergence record the first meal actually accepted and each youngster’s growth while continuing to follow female recovery. Over time these records help identify your lineage’s pattern without turning approximate durations into deadlines.
