Check a golden gecko mostly by watching, not handling: after dark it should move fast and surely on the glass, hunt with intent, show clear eyes and clean skin with no retained shed on the toes, and carry a tail base that is not pinched or thin. Note any gecko that stays exposed and sluggish in daylight, breathes with…

Check a crested gecko after dark, when it is awake: it should climb and stick to smooth surfaces confidently, lick its eyes clean, visit its food dish with visible lick marks, and carry a straight, firm tail with no sunken look around the eyes. Inspect the toe pads for retained shed, watch a jump land cleanly, and…

Check a corn snake by letting it travel through your hands over a table: movement should be smooth and strong, eyes clear outside a shed, breathing silent, and scales glossy with no mites, lifted patches, or retained skin on the tail tip. Feel for unexpected lumps, check the vent sits flat and clean, and confirm the…

Check a blue tongue skink while it is out basking or feeding: eyes should be bright, the mouth should open to show a healthy pink interior and that blue tongue without excess saliva, all toes should be free of tight retained shed, and the body should feel solid with a thick tail base. Watch it walk for an even, low…

Check a bearded dragon on its basking schedule in bright light: eyes should be bright and open, the beard and body free of retained shed and swelling, the mouth closed cleanly without stringy saliva, and the tail base and hips plump rather than bony. Watch it walk a short distance for an even gait, feel the belly…

Do the check in a warm, quiet room with the ball python moving slowly through your hands: look for clear eyes outside a shed, a clean mouth line, smooth scales with no mites around the chin and eyes, and a rounded body that does not feel flabby or show a prominent spine. Listen for silent breathing, glance at the vent…

A leopard gecko in discomfort often stops hunting at dusk, leaves its fat tail thinning as it draws on reserves, stays in its hide instead of wandering, and may squeak, bite, or jerk away when a sore spot is touched, behaviours this usually placid species rarely shows. Stuck shed tightening on the toes, a swollen…

A corn snake in discomfort often becomes uncharacteristically restless or, at the other extreme, limp and unresponsive when handled, and it may refuse feeds, soak repeatedly, or writhe and twist oddly instead of moving in smooth waves. Jerky striking at nothing, rubbing the face on decor, gaping, and audible breathing…

A blue-tongued skink in discomfort typically withdraws from its usual bold routine: it may stay buried instead of emerging to bask and eat, hiss and display its blue tongue at handling it once tolerated, refuse favourite foods, and move with a stiff, low crawl or avoid putting weight through one leg. Dull, retained…

A ball python in discomfort usually stops doing its normal quiet things: it may refuse meals it normally takes, stay restlessly active in daylight, soak for long periods, hold its body in an unusual tense or flattened posture, or flinch and pull away sharply when a particular area is touched. Wheezing, bubbles at the…

White's tree frogs commonly develop bacterial skin infections, bloating linked to water quality or internal problems, metabolic bone disease, chytrid fungal infection, eye cloudiness, and weight gain from their famously enthusiastic appetites. A frog that develops puffy, fluid-looking swelling, stops climbing to its…

Rosy boas are hardy desert snakes, and their common problems are mostly husbandry-linked: respiratory infections in cool, damp setups, mouth rot, snake mites, retained shed, and regurgitation when a meal is too large or the snake is handled too soon afterwards. A rosy boa that bubbles at the nose, wheezes, or keeps…

Rainbow boas most often develop respiratory infections, mouth rot, snake mites, retained shed, and regurgitation, and nearly all of these connect to their demanding humidity needs. A Brazilian rainbow boa kept too dry sheds in torn patches and may refuse food, while one kept damp and cool can start wheezing or blowing…

Painted turtles most commonly develop shell rot, respiratory infections, and swollen eyes from vitamin A deficiency, along with a distinctive ear abscess that swells the side of the head. This is a hardy species, but it still needs what wild painted turtles get daily: clean water, a dry basking dock under proper…

Long-tailed lizards most commonly lose their famously long tails to rough handling and tankmate nips, trap shed on their slender toes, and develop metabolic bone disease without proper light and calcium. That tail can be most of the animal's length, and it regrows shorter and plainer, so handling by the body — never…

Leopard tortoises most commonly develop pyramided, uneven shells, respiratory infections that announce themselves as a runny nose, and bladder stones, and all three grow out of diet and climate — this is a dry-grassland grazer often kept too humid and fed too richly. A smooth-shelled tortoise needs high-fiber grasses,…

Hognose snakes most commonly worry their owners with feeding strikes, while their genuine health problems are respiratory infections, mouth rot, retained shed, and mites. The hard part is telling theater from illness in a snake famous for bluffing, hissing, and playing dead. A seasonal fast in a plump, alert hognose…

Green anoles most commonly suffer stress and dehydration, metabolic bone disease, and stuck shed, and in such a small lizard each one moves fast. An anole that stays brown for days, stops drinking droplets, or lets its hip bones show is declining, not merely moody. Mist for drinking, screen out cage-mate bullying, and…

Giant day geckos most commonly suffer torn skin from handling, metabolic bone problems from calcium shortfalls, and stuck shed on their toes, because this is a display species whose skin is built to tear away from predators. Add egg-binding in breeding females and weight gain on rich fruit diets, and most of the list…

Garter snakes most commonly develop mouth and respiratory infections, blister-like scale disease in damp enclosures, and a specific vitamin problem tied to fish-heavy diets, because some feeder fish contain an enzyme that destroys vitamin B1. A garter that refuses fish, drools or shows a cheesy mouth lining, or…

Five-lined skinks most often face tail loss and problems regrowing it, shed skin trapped on their very small toes, and internal parasites, since many in the trade are wild-caught. A dropped tail is a defense, not a disaster, but the stump must stay clean while the shorter, duller replacement grows in. Check toes after…

Common musk turtles most often develop shell rot, respiratory infections, and swollen, shut eyes linked to vitamin A deficiency, and nearly all of it traces back to water quality in a species that spends almost its whole life submerged. Soft or pitted patches on the shell, wheezing at the surface, and refusing food…

Children's pythons commonly develop breathing infections when kept too cool, retained shed when the air is too dry, and burns or mite problems around poorly guarded heat sources. Mouth inflammation, scale irritation in damp substrate, and stress-related feeding refusals round out the usual list for this small…

Boa constrictors most often run into breathing infections, retained shed, mite infestations, and mouth or belly skin infections, usually when heat or humidity drifts off range. Serious keepers also watch for a viral illness that affects movement and feeding, and for regurgitation linked to meals that are too large or…
