There were a number of terrariums that was installed in the Aquarium building; two cabinets filled with several smaller terrariums, one large terrarium with reticulated python, and four smaller individual terrarium. One of these smaller terrarium houses a pair of baby snake-necked turtles, which I believe you have posted already here.
I have no idea if the skinks are new or not after your visit, but they're certainly there. I will talk about it in the Indonesian forum.
