The elongated tortoise (Indotestudo elongata) is a medium-sized species from the forests of Southeast Asia and India. It is less commonly kept than sulcata or Hermann’s tortoises but is well-regarded among tortoise enthusiasts for its manageable size, curious temperament, and distinctive flattened shell. This guide covers everything needed for successful long-term care.

The elongated tortoise is classified as Endangered on the IUCN Red List, primarily due to habitat loss and collection for the wild food and pet trade across its Southeast Asian range. Always source captive-bred animals from reputable breeders and check the legal requirements for ownership in your region before acquiring one.
Appearance and Colours
The common name is an accurate description. The shell is notably longer and more compressed than that of most tortoise species. It is flat rather than highly domed, and distinctly oval when viewed from above. The scutes are relatively smooth and feature a tannish-yellow base with irregular dark brown to black blotches, producing a muted but attractive pattern that is unique to the species.
The front legs carry large protective scales while the hind legs are comparatively smooth. Both males and females develop a pinkish colouration around the snout during breeding season. The head is rounded and typical of the genus, with pale tan skin.
Sexual differences are subtle but present. Females tend to be slightly wider with a rounder shell profile and a flatter rear plastron. Females also develop noticeably long curved claws, which are thought to assist with nest excavation.
Elongated Tortoise Size
Adults typically reach 12 to 14 inches in shell length, with females more likely to reach the upper end of that range. Weight is usually around 7 pounds. As a medium-sized species, elongated tortoises are more manageable than sulcatas or other large tortoise species, but they still need a substantial enclosure with room to roam.
Lifespan
The average lifespan in captivity is 40 to 50 years with proper care. Tortoises as a group are long-lived, and acquiring one is a significant commitment. Poor enclosure conditions and inadequate diet are the most common reasons captive elongated tortoises fail to reach their potential lifespan.

Elongated Tortoise Care
Elongated tortoise care is intermediate in difficulty. The husbandry requirements are not unusually complex, but this species does have specific humidity and temperature needs that must be maintained consistently, and the enclosure size requirement is larger than beginners often expect.
Enclosure Size
Elongated tortoises can be kept indoors or outdoors depending on climate. Outdoor enclosures are preferable for keepers in warmer regions. This species thrives with access to natural sunlight and the enrichment of a naturalistic outdoor space. In cooler climates, an indoor setup is needed for winter months at minimum.
The minimum indoor enclosure is 6 feet wide by 8 feet long with walls 12 to 24 inches high. Large agricultural stock tanks work well for this purpose. Outdoor pens should meet the same minimum dimensions, with solid opaque walls to prevent the tortoise from seeing out and becoming motivated to escape. Extend walls below ground level to prevent digging escapes.
More space is always better. Elongated tortoises are active foragers in the wild and will use additional space purposefully rather than simply sitting in a larger enclosure.
Habitat Setup
The goal is to replicate the humid, forested floor of the tortoise’s natural habitat. Unlike species that spend time basking in open sun, elongated tortoises prefer to forage through leaf litter and bury themselves in moist substrate. The enclosure should reflect that.
Substrate: Use an absorbent material capable of holding moisture. A mixture of coco coir and peat moss works well, with a top layer of sphagnum moss and leaf litter to slow evaporation. Avoid cedar shavings or any bark that can harbour toxins. Depth should be 6 to 10 inches for adults to allow burrowing. One side of the enclosure should be kept consistently damp while the other is drier, giving the tortoise a choice.
Plants: Dense tropical plants and grasses are appropriate. Aim to create good shade cover throughout the enclosure. Avoid any species that produce toxic seeds, berries, or leaves. The shade serves a dual purpose: it cools the enclosure and provides the sense of cover elongated tortoises seek in their natural forest habitat.
Hides: Provide at least one enclosed hide on the cooler, damper side of the enclosure. Elongated tortoises will use these during the heat of the day and when they want to feel secure.
Temperature and Lighting
- Ambient daytime temperature: around 75°F
- Basking spot: 85 to 90°F on one side of the enclosure
- Nighttime: 60 to 65°F minimum. Below this, a ceramic heat emitter or indoor relocation is needed
Elongated tortoises are crepuscular rather than dedicated baskers, but a basking area is still necessary for thermoregulation. A basking lamp on a timer covering one side of the enclosure creates the temperature gradient the tortoise needs to self-regulate throughout the day.
For indoor enclosures, a UVB lamp is essential. Reptiles require UV exposure to synthesise vitamin D3 for calcium metabolism. A T5 HO UVB tube positioned over the enclosure on a 12-hour cycle is appropriate. Outdoor tortoises receive sufficient UV from natural sunlight and do not need supplemental UVB.
Humidity
Aim for 60 to 80 percent relative humidity throughout the enclosure. This species comes from humid tropical forests and will suffer in chronically dry conditions. Respiratory infections and dehydration both become risks when humidity drops below 50 percent. Misting the substrate once or twice daily and maintaining the moisture-retaining substrate mix described above should be sufficient to maintain appropriate levels. Monitor with a digital hygrometer rather than relying on estimates.
Water
Provide a shallow water dish large enough for the tortoise to step into and soak. Elongated tortoises are not swimmers and the dish must be shallow enough that the tortoise cannot tip and become trapped underwater. They will use the dish to drink, soak for hydration, and occasionally defecate in it. Check and clean it daily. A soiled water dish is a rapid source of bacterial contamination.
Food and Diet
Elongated tortoises are omnivores, one of the relatively few tortoise species that regularly eat animal protein in the wild in addition to plant material. In captivity the diet is primarily plant-based with protein offered twice weekly.
Plant foods (roughly 75% of diet): dark leafy greens are the best base. Dandelion greens, collard greens, mustard greens, and endive are all nutritious options. Squash, zucchini, green beans, sweet potato, and peas work well as vegetable variety. Fruit (apple, banana, pear, watermelon, cantaloupe) can make up the remaining portion of plant foods but should not dominate. Fruit is high in sugar and should be offered in moderation.
Protein (twice weekly): earthworms, crickets, and thawed pinky mice are all accepted. The protein component mimics the carrion and invertebrates these tortoises opportunistically consume in the wild.
Supplements: dust food with calcium powder several times per week. A multivitamin supplement can be added once weekly. Calcium is particularly important for females during and after egg production.
Variety is the priority. Feeding the same few items repeatedly creates nutritional gaps and produces picky eaters. Rotating through a wide range of appropriate foods within these categories gives the best nutritional coverage.
Potential Health Issues
Respiratory infections are the most common health problem and are almost always linked to improper temperature or humidity. Signs include nasal discharge, laboured breathing, and lethargy. Correct the environmental conditions and consult a reptile vet for antibiotic treatment.
Shell rot and skin infections are caused by bacterial or fungal growth, typically in animals kept in dirty or persistently waterlogged conditions. Spot clean the enclosure daily and do a thorough sanitisation of all surfaces monthly to prevent bacterial buildup. In severe cases shell infections can penetrate through the shell itself.
Metabolic bone disease (MBD) results from insufficient calcium or UVB exposure. Signs include soft shell, deformed growth, and weakness. Preventable with consistent calcium supplementation and adequate UV access for indoor tortoises.
Find a reptile-experienced vet before problems arise. Many general practice vets have limited experience with tortoises and a specialist makes a significant difference in treatment outcomes.
Behaviour and Temperament
Elongated tortoises are generally docile and non-aggressive. Male and female pairs can be kept together without significant problems. Two males are more likely to cause issues. Some males become territorial, particularly during the breeding season when males may bite and headbutt females persistently. This behaviour is temporary and subsides after the breeding season, but it should be monitored and the animals separated if the female is showing signs of stress or injury.
Day to day, elongated tortoises spend their time foraging, exploring, and burrowing into the substrate. They are active and inquisitive compared to many tortoise species. Inspect the enclosure perimeter regularly. Any gap or weakness in the walls will be found and investigated.
With time, individual tortoises often recognise their keeper and will approach for food. Some tolerate light head scratching. This level of familiarity develops over months and years rather than weeks, and should not be forced.
Handling
Elongated tortoises tolerate brief handling but do not enjoy extended time off the ground. Keep handling sessions short and infrequent. Excessive handling causes stress and may result in the tortoise refusing food. A light bite is possible if the tortoise feels threatened, though this species is not aggressive by default. Let interaction happen on the tortoise’s terms. Allowing it to walk up to you during enclosure maintenance or feeding builds more trust than regular forced handling.
How big do elongated tortoises get?
Adult elongated tortoises typically reach 12 to 14 inches in shell length and weigh around 7 pounds. Females tend to reach the larger end of the size range. As a medium-sized species they are more manageable than large tortoises like sulcatas, but still require a substantial enclosure.
How long do elongated tortoises live?
Elongated tortoises live 40 to 50 years in captivity with proper care. Like all tortoises they are a very long-term commitment. Diet quality and enclosure conditions are the main factors determining whether a captive animal reaches the upper end of that lifespan.
What do elongated tortoises eat?
Elongated tortoises are omnivores. The captive diet should be roughly 75 percent plant-based (dark leafy greens, vegetables, and some fruit) with animal protein offered twice weekly in the form of earthworms, crickets, or thawed pinky mice. Calcium powder should be dusted on food several times per week.
Are elongated tortoises endangered?
Yes. The elongated tortoise is listed as Endangered on the IUCN Red List. The primary threats are habitat loss and collection from wild populations for the food and pet trade across Southeast Asia. Always purchase captive-bred animals from reputable breeders and confirm the legal status of ownership in your region before acquiring one.
What humidity do elongated tortoises need?
Elongated tortoises require 60 to 80 percent relative humidity. They come from humid tropical forests and will develop respiratory infections and dehydration if kept in chronically dry conditions. Misting the substrate once or twice daily and using moisture-retaining substrate materials (coco coir, peat moss, leaf litter) maintains appropriate levels.
