Everett. Juvenile Parson’s Chameleons (Calumma parsonii) are rare, slow-growing gems in the chameleon world—especially prized for their massive adult size, long lifespan, and calm demeanor. At the juvenile stage, they’re delicate but full of potential. Here’s a detailed breakdown tailored to your level:
🦎 Species Snapshot: Juvenile Parson’s Chameleon
| Attribute | Details |
|---|---|
| Age Range | ~6 to 12 months |
| Size | ~5–8 inches (12–20 cm) total length |
| Weight | ~30–60 grams |
| Growth Rate | Very slow—takes 2–3 years to reach full adult size |
| Lifespan | 10–15 years in captivity (among the longest-lived chameleons) |
Most breeders won’t release juveniles until they’re at least 6 months old, due to their sensitivity and slow acclimation.
🎨 Coloration & Morphs
Juveniles are typically green to bluish-green, with faint diagonal striping and subtle eye turret coloration. As they mature, they develop into one of several morphs:
- Orange Eye (OE): Copper-orange eye turrets, green body
- Yellow Lip: Yellow facial markings, turquoise body
- Yellow Giant: Larger-bodied, bold green with yellow accents
- Cristifer: Smaller subspecies with dorsal crest and blue hues
Coloration is subtle in juveniles but begins to intensify around 12–18 months.
🏡 Enclosure & Setup
- Minimum Size: 18x18x36 in for juveniles; adults require 24x24x48 in or larger
- Lighting: T5 HO UVB (Arcadia or Zoo Med) + basking bulb
- Temps:
- Basking: ~85°F (29°C)
- Ambient: ~72–78°F (22–25°C)
- Night: ~65°F (18°C)
- Humidity: 70–90%; mist 2–3x daily or use automated fogging
- Plants: Ficus, Schefflera, Hibiscus, and Pothos for hydration and cover
Parson’s juveniles need stable hydration, gentle airflow, and minimal stress—they’re more sensitive than Panther juveniles.
🍽️ Diet & Feeding
- Staples: Gut-loaded crickets, roaches, silkworms, BSFL
- Treats: Hornworms, waxworms (sparingly)
- Dusting Schedule:
- Calcium (no D3): 3x/week
- Multivitamin with D3: 2x/month
- Bee pollen: every feeding
Feed daily, adjusting prey size to match the width of the chameleon’s head. Juveniles can be picky eaters, especially during acclimation.
🧠 Behavior & Handling
- Temperament: Calm but shy; easily stressed by overhandling
- Handling: Minimal—focus on observation and slow acclimation
- Socialization: Always housed solo; visual isolation preferred
