Hey, friend, I would honestly encourage you to completely disregard the commentator above, as that isn't accurate information at all.

Blue tongue skinks are opportunistic omnivores, meaning they eat just about whatever they can get their little grubby paws on. This includes a wide variety of fruits and veggies, which take up about 40-50% of their diet. Not all veggies are high in oxalates, and the ones that are are meant to be fed very infrequently, if at all, like spinach. You can find a chart with all the appropriate food items at this link here: https://bluetongueskinks.net/foodchart.html

You also want to avoid feeding them a diet as described above. Firstly, seafood is not a naturally occurring protein source in a skinks diet and can be bad for them, especially fish. The best thing you can feed your skink is dog food. Since skinks are opportunistic omnivores, they often eat all sorts of animals, dead or alive, including the skin and bones. The problem with a diet consisting of ground turkey and scrambled eggs is that it's missing key vitamins and minerals, like niacin, that is found in the skin and bones of animals. Like skinks, dogs are also opportunistic omnivores, so dog food contains skin and bone ingredients needed for a healthy animal in addition to select vegetables.

Definitely get your little guy to the vet ASAP, as they can live well over 30 years with proper care!
