@EternalPigeon They look way to chunky too be that, also do you if the one at the back is the same species or not, it just be inter-specific variation but it looks quite different to the other 2.
On a more recent visit, I was at this exhibit in time to see these skinks (as well as the Emerald Tree Monitors) being fed. I took the opportunity to ask the keeper what species they are - they said they are Major Skinks (Bellatorias frerei).
