That is absolutely not a tokay. Tokay's bark and bite. They are nasty little ones and are a beautiful blue/green with orange spots and eyes. They are also quite large. That is a golden gecko. We had one for years. They are absolutely fine in a 10 - 20 gallon tank. You will need a screen top and some daygloe and nightglo bulbs. A heat rock will be perfectly fine. Also you will need a hiding place and some plant. They like to climb. Never feed them mealworms as they do not have enough protein and vitamins and cause bones to become soft and easily broken. Crickets are their staple diet and they should be feed 3-5 crickets every 2-3 days. Also every second or third feeding the crickets need to be dusted with a calcium supplement called "reptical". Friut is ok for a treat for them now and then our just loved peach and pears. But only as a treat because if they really like them they may stop eating the crickets and they NEED them. A small shallow dish of water is good to have in their tank at all times. And a good substrate (bedding) is corn cob bedding. It's natural and non-toxic and it doesn't prevent them from climbing like a sand would do. I hope this helps.
