A red-eared terrapin.

Aquatic and semi-aquatic turtles are popular as pets. The most well known is probably the red eared slider, although there are several other species which are kept as pets.
Size and Life Span.
Many people also do not realize how big aquatic turtles can get. Red eared sliders and a couple of the other commonly available pet species will grow to at least 10-12 inches long and thus will require correspondingly large enclosures. All turtles have the potential to enjoy a very long life span (i.e. several decades!) if cared for properly.

Housing.
Aquatic turtles require fairly elaborate housing. They need regular exposure to ultraviolet (UV) light, so pricey bulbs designed for reptiles that produce UVA and UVB light are needed for turtle tanks. Without this light, metabolic bone disease (soft shell syndrome) can result.
Turtles are messy, and a good filtration unit will be necessary to help maintain water quality, as will regular cleaning. They should have deep enough water to allow swimming, along with a place to get out of the water to bask (heated from above with a basking light.) In
addition, appropriate water and ambient temperatures should be maintained.

Feeding.
Although turtle foods have come a long way they are not recommended as a sole source of food for aquatic turtles. Most are omnivores (and preferences for different foods might change at different points in the life cycle), and offering a good variety of foods is the best way to feed most turtles. As a rule, feeding turtles in a separate plastic tub will allow the mess associated with feeding to be contained (turtles are messy eaters, and this will reduce the need for tank cleaning a bit) and allow monitoring of food intake of each turtle if multiple turtles are kept.

The Indian Star Tortoise.





Description: Star Tortoises have a yellow or tan head. Females
are much larger than males and have a shell which is
much broader.
Lifespan: Up to 80 years
Estimated Size: Up to 12"
Natural Location: India

Feeding & Water.
The best way to feed your Star Tortoise is to allow it long periods of grazzing time. It will happily forage around your yard for several hoursa day. If you are going to allow your tortoise to graze in your yard you will not be able to use any sort of pesticides on your lawn or in your garden. Greens such as turnips and collards can be fed a couple of times per week. In addition, carrots, potatos and squash can also be offered, although this should not be done more than once per week. Some fruits such as apples, peaches, bananas and strawberries work well in smaller quantities to offer a variety in the diet of your Star Tortoise.

Temperature & Lighting.
The optimal temperature for Star Tortoises is between 75 degrees F and 85 degrees F during the day and between 75 degrees F and 78 degrees F at night. Since Star Tortoises are not supposed to hibernate in the winter, you must provide them with a warm enough temperature that they do not attempt to do so. In the winter ensure that the daytime temperature does not dip below 70 degrees F during the day. A drop in nightime temperature is acceptable as long as it is not more than about 5 degrees F.

Housing.
If their enclosure is too damp it can easily lead to skin infections in Star Tortoises as they are not adapted for wet conditions.
Although Star Tortoises are not that large, they require a fair bit of room to graze as they like to move around a fair bit. Keeping your Star Tortoise outside will provide it with plenty of room to move about. Star Tortoises are not known for their digging capabilities however you should still ensure that their enclosure does not permit escape.
