I noticed that not many of you use the word 'terrarium'.Some say 'tank',some say 'viv',and maybe some other words. Now for those of you who call your reptile's home 'tank',do you mean a fishtank?And what's a 'viv'? Here in Switzerland people don't keep their snakes or others in fishtanks,because the all glass terrariums are very popular and you get them everywhere at petstores! I read very early on when starting to learn about snake keeping,that you should'nt use a fish tank,but a terrarium with sliding doors,and there are more reasons for this. 1.In a fishtank you don't get the air circulation right,and this can become a problem. 2.you shouldn't keep snakes in a fishtank,because then you have to get the snake out from above,and this causes more stress for the snake,because of the instinct of being afraid of the birds who get them in the wild! I'm very curious to find out why so many of you keep the reptiles in a tank.Or do you really mean 'terrarium' with the sliding doors??? Confusion! Or are terrariums like we know it here not popular in America? I think the only person I saw on this forum using the word 'terrarium' was BlackJack! And as you know from her great pics,it's a huge one with sliding doors! Maybe someone can explain this to me!Thanks!
