Crested gecko — the apartment lizard
If you live in a 600-square-foot apartment, want a lizard, and don't want to deal with heat lamps or daily insect feeding, the crested gecko is built for you.
What works:
- Room temperature is the target. 72-78°F. Most living rooms qualify already. No basking lamp required.
- Commercial diet works as the staple. Pangea or Repashy powder mixed with water, fed 3 times a week. Insects are optional variety.
- Small footprint. 18×18×24 inch enclosure fits on a desk.
- Arboreal behavior is visible and interesting. Climbs vines, sleeps in foliage, hunts at night.
What you sign up for:
- Fragile skin. Crested geckos drop tails when stressed and don't regenerate them (unlike leopard geckos). Handling is occasional, not regular.
- Nocturnal. If you want to watch your lizard while you're awake, you'll see less of it.
- Humidity matters. 60-80% with daily misting. Not as forgiving as desert species.
Leopard gecko — the easiest first reptile
If you want the lowest-stress entry to reptile keeping, this is it.
What works:
- Simple husbandry. Warm side 88-92°F, cool side 75°F, ambient room temperature, modest humidity. Easy to dial in.
- Hardy. Forgiving of small mistakes. Long lifespan with reasonable care.
- Moderate handling tolerance. Most leopard geckos handle 1-2x per week comfortably after acclimation.
- Small footprint. 36×18×18 inch enclosure works for adults.
- UVB debate is now settled. Modern care recommends low-output UVB even though leopard geckos historically did "fine" without it. Reasonable T5 HO 5.0 covers it.
What you sign up for:
- Insect-only diet. You'll be buying or breeding crickets, dubia, or BSFL. Mealworms are not a staple — see our impaction mistakes article.
- Crepuscular activity. Most visible at dawn and dusk. Less active during the day than a bearded dragon.
Bearded dragon — the most interactive starter
If you want a lizard you can hold, watch all day, and form a real bond with, this is the only choice among the three. The trade-off is cost and lighting complexity.
What works:
- Diurnal and active. Awake when you are. Visible, engaged, interactive.
- Strongest handling tolerance. Generally docile, comfortable being held, recognize keepers individually.
- Omnivorous and varied diet. Insects, vegetables, occasional fruit — interesting to feed.
- Substantial size. 16-24 inches as adults. A "real" pet lizard.
What you sign up for:
- Mandatory high-output UVB. T5 HO 12% bulb across most of the enclosure. Replaced every 6-12 months. This is not optional — without proper UVB, the dragon develops metabolic bone disease. See our MBD article for the specifics.
- Large enclosure required. 48×24×24 inches minimum for adults.
- Higher setup cost. $500-800 to do it right — enclosure, T5 HO fixture and bulb, dimming thermostat, basking lamp, decor.
- Higher ongoing food cost. Daily fresh greens plus insects.
