Is it bad to give my tortoise those tortoise food pellet things?
No they should be made full of the right ingredients that your tortoise needs.
An ideal diet for tortoises is their natural diet of weeds and herbs. There are several complete processed foods available for tortoises. These are convenient and easy to make up, although should be supplemented with a variety of fresh, natural leafy greens. In fact tortoises can be fed entirely on a natural diet of weeds and herbs. In all cases they require high fibre, low protein and low sugar. Tortoises will also require daily calcium and vitamin supplements, which should be given alternately.
Different types of lettuce should be offered as well as a varying mixture of water cress, rocket, grated carrot, chopped sweet pepper and weeds like dandelion, clover and plantain. Always wash any plants, so they are clean and free from pesticides. It is important to provide a variety of plants, just like they would find in their natural environment, and like humans, they have their preferences.
Small quantities of fruit and vegetables can be given as treat. These include, strawberries, apples, spring greens, kale, broccoli and spinach, but should only be given occasionally as they can irritate their digestive system. Don’t forget to give them plenty of fresh water in a shallow dish, which will need to be changed daily or sooner if they have used it as a toilet!
Plants and flowers that grow from bulbs, such as daffodils are toxic and can cause death. Rhubarb leaves are also poisonous, and soft fruits like bananas can also cause digestive problems.
To give your tortoise the best possible diet, we recommend that you research what food can and must not be fed to tortoises.
What's the best thing to protect the floor of the tortoise box?
I use a towel under any of my tanks to keep the surfaces clean, dry and undamaged from my tanks or other animal containers.
You could always buy a specialist tortoise stand to keep it on or use a surface that you don't mind if somethings happens to it.
Should you put calcium on the food of my tortoise?
Read the instructions and ingredients of the food you use as some of these are already in it, you don't want to over feed it.
how long should it be under the special light?
Tortoises have to have a heater and UV light to help them get there recommended vitamins and to help keep them healthy. Your heater should always be on and your UV light should be on as if it were the sun (7am-8pm) normal daylight times as the UV is an artificial sun.
should i still give him baths? how often?
Tortoises cannot groom themselves, so appreciate a lukewarm bath 2-3 times a week, this should only be up to the depth of their lower shell (the Plastron). A soft toothbrush can be used to clean their shells in water, never use any oils or other chemicals, as they can damage their shells.
Tortoises can urinate in high volumes so it is essential their housing is spot cleaned daily, removing any soiled bedding and faeces. A tortoise fed on the correct diet produces compact, fibrous faeces which are easy to remove. Make sure you have a full clean of the housing every week.
Do not submerge a tortoise in water as they can drown and it can damage there shell.
Is it bad that i hand feed him?
Hand feeding any animal is alright and can help tame them.
When should he start hibernating? is it 5 or 6 years?
In the wild tortoises should hibernate from when they are hatch-lings but when keeping a tortoise as a household pet they recommend getting them ready to hibernate around the age of 3 years old.

I would recommend researching and learning about animals before purchasing as there are so many different species and types that need specialist care and information. There are lots of Facebook groups that can help with caring for your tortoise and even books. I wouldn't always recommend asking in a pet store though as my pet store tried to sell me lots of tortoise items, food etc, when I have a turtle and they are completely different animals, one eats meat, the other eats veg, one lives in water, the other live on land etc.
Best of Luck with your tortoise.
