Hi,
I've had a pink tongue since just before Christmas so I'm definitely not an expert, just keep that in mind.
What I've learnt so far is that its very similar to blue tongue care, which you'll be able to find lot of information about. The main differences I've noticed (not having kept blue tongues) is that they are excellent climbers and that you will need to source snails or slugs for their diet. This makes up something like 70% of their diet in the wild so they need quite a lot, although mine seems to be doing ok on a bit less than what I should probably be giving him. When I first got him I picked up a can of exoterra snails and fed him those. It took a little while for him to try them becuase he had previously been eating live snails but he seemed to thrive ok on those for a couple of months. I also have a large garden with lots of snails in it. Since we don't use any pesticides ect I grabbed some of those, purged them (fed them carrots till their excrement was orange and then straved them), froze them for a month and then cut them up for him to eat over the next couple of weeks. I'm hoping these will have a little more nutrients then the canned ones.
As well as snails and slugs they eat a lot of different types of veg, I suggest you get a frozen pack of mized diced veg and keep that handy. Mine likes peas and corn especially and will eat (softened) carrot, and a few other things I chuck in now and then. He also likes cut of grapes, plum and nectarine. You have to be careful with some fruit and vege like lettuce and tomato as they are mainly water and don't have that many nutrients (apparently). Mine will also eat mealworms now and then which is a good addition, but I've heard a lot of people saying theirs wouldnt touch them. Mine ignored crickets completely. I don't know if you have other lizards but you will need a calcium supplement for its scales to grow properly after each time it sheds.
Apart from that its pretty standard lizard care. You just have to be careful with their climbing as mine has travelled all the way up my curtains and had fun in the curtain rings like a snake. They can be very surprising, especially if you are used to blue tongues.
Let me know if you have anymore questions as I know I had trouble getting information too when I was looking at getting mine.
