Pairs work, but keep males strictly separate. The reason: several males fight over territory and basking spot until one is injured or sits permanently in a corner. Females usually tolerate each other but need separate heat and hiding spots each; feed separately if sizes differ.

Notes

Split from V. pilbarensis in 2014. A pure rock-crevice dweller – the stone structures must offer narrow crevices and be built absolutely stably.
