kobson as goldmember stated you would be better off doing some research on husbandry & keeping reptiles in captivity since you said yourself you have no experience keeping snakes. In your other thread when you first joined the site this month you also say you dont have a reptile licence yet.
reptiles can thrive in different types and size enclosures or tubs as long as they have sufficent heating and access to a hotter and cooler area, water, a hide and food. Some reptiles actually do better in smaller sized enclosures while other may do better in larger ones. All reptiles are individuals and although we can make generalisations about a particular species and their husbandry theres always exceptions. Anthropomorphism is any attribution of human characteristics (or characteristics assumed to belong only to humans) to animals. and what people think makes a snake "happy" is really what makes the person happy and what one person may see as cruel may not be seen the same by another person. Its very easy to make incorrect assumptions and judge others when you dont know enough about them or the subject your discussing.
If you are looking to learn about reptiles my suggestion is to turn off youtube for a start. theres some great stuff on there but probably way more rubbish. I suggest some books such as Keeping and Breeding Australian Pythons or Keeping and Breeding Australian Lizards edited by Mike Swan or Care of Australian Reptiles in Captivity by John Weigel. And go through some of the threads on forums like this one.
