skinks have blue tails
This question cannot be answered, because no species of skink was identified. Skinks are a large family of lizards, and range from tiny forest-floor dwelling insectivores to large tree-dwelling herbivores, and everything in between. Popular pet skinks include fire skinks (insectivores), blue-tongued skinks (omnivores), and monkey-tailed skinks (herbivores).
They eat metalwork crickets and any other type of insects. If they are thirsty, they will drank water.
