It inhabits the Indo-West Pacific, near Thailand, Myanmar, Indonesia, Papua New Guinea, and Australia.

[1] It is found on algae-covered rocky surfaces and gorgonian sea fans at depths of 5 to 20 metres (16 to 66 ft), where it can grow to lengths of around 7 centimetres (2.8 in).

This species is ovoviviparous, with males brooding when they are at lengths of 5 to 5.5 centimetres (2.0 to 2.2 in).

[2] The specific name and common name honour the late Italian prime minister Benedetto Craxi (1934-2000).

[2] It may be identified by its body pattern of 12 thin white bars along the length of its body, each preceded by a thick red bar.
