Getting there
Steady to a large adult
They become a substantial gecko, and the enclosure needs to be planned accordingly rather than started small.
The voice comes with maturity
The loud call the species is named for is a mature male trait, and it is genuinely loud.
What that size means in practice
A tall, secure enclosure
They are arboreal and powerful, and a large tokay needs a well-secured vertical space with plenty of cover to retreat into.
Cover reduces the defensiveness
A tokay with enough hides is a calmer animal than one with nowhere to go. Furnishing is a welfare measure rather than decoration.
