Fresh water should be supplied on a daily basis for most lizards. Make sure your Argentine black and white tegu gets ample water to soak in if desired, much as other tegu species. The moisture from the soil and vegetation around it is sufficient for this purpose.
In general, avoid supplying your lizard with too much water or any water that is not clean. Both can be fatal if provided regularly. Make sure any water you do provide is at least partially covered so it does not go directly onto the floor or ground where it could be tracked into another area of the house by your lizard.
If your lizard falls into a pool of water, try to get him out as soon as possible. Even small amounts of water in the lungs can cause death due to asphyxiation. You may need to take it slow when getting him out because he might be scared and unwilling to move. A long-handled net would be helpful here.
Lizards like sunlight too. If you want to provide your lizard with additional light during the day, consider installing a light fixture with a shade covering part of the bulb. This will allow some light into the room while still providing relief from the heat of the sun. Just make sure the shade is large enough to cover your lizard's home without blocking its view of the outside world.
Things to keep in mind when caring for tadpoles Tadpoles, like fish, will require regular water changes, especially if housed in an aquarium or bowl. This should be done at least twice a week because if the water becomes too unclean, it might turn toxic and the tadpoles will die. Cleaning your container every day is also important so that you do not contaminate one area of your tank with feces or algae products which could harm other animals if they consumed them.
Tadpoles need clean water that is between 65 and 70 degrees Fahrenheit (18 and 21 degrees Celsius). The water should be slightly acidic (6.2-7.2 pH) but not overly so (less than 5.5). If your water is completely flat, then you need to buy some acid drops or add vinegar to raise the pH. You can use fruit juice, wine, or vegetable broth instead if you do not want to purchase acid drops.
You should also test your water occasionally to make sure it is still clean and doesn't contain any harmful chemicals. If it does, change your water immediately!
Tadpoles like clean air as well, so make sure there are no poisonous gases leaking from anywhere in the room where you are keeping them. Also, avoid using perfume or other scented items since this will fill the room with toxic fumes that could be fatal to your tadpoles.
Young skinks may be fed ad libitum on a regular basis; as they get older, they may be fed just every other day. They require constant access to clean drinking water as well as a vitamin/mineral supplement including vitamin D3 (offered twice a week to adults and every other day to growing juveniles). They're huge lizards! Feeding skinks doesn't provide all of their nutrition needs, but it does help them to grow at a healthy rate.
The skink's digestive system is very simple but effective. Their stomach is small but powerful; it can digest and absorb nutrients from food that would otherwise be passed out through the feces. Skinks have a second stomach called the hepatopancreas that functions much like our liver - removing toxins from the body. These organs are located in the tail region of the lizard.
Like all lizards, skinks are amphibious animals which means they can breathe both air and water. However, they are more aquatic than most lizards because they need to search for their food each day instead of being able to hunt like mammals do. They are also vulnerable to drying out because they don't retain heat like reptiles do. If you live in an area where there is no water available during times of drought, consider using natural alternatives such as crushed eggshells or even milk cartons with holes poked in them. This will help ensure your pet has enough to drink even if there isn't any water around.
