My old Snake Todd died a few days ago and i had to sell my snake tank because it was badly scratched from the twigs i put in so know i want to know should i get a Gecko or another Snake?
Why did your snake die? This would be a good question to answer. Most snakes can live up to 20 years or more in captivity. If there was some husbandry issue that caused your snake's death, you need to fully understand how to solve that problem before you get another reptile.
Slow down. Getting a "replacement" pet isn't a good idea. When they aren't just like your Fluffy (or whatever), you end up disappointed.
If your going to get a gecko than don't put sand in the tank because it will digest the sand and it will die.
