保育: Metriaclima emmiltos 由国际自然保护联盟（IUCN）在濒危物种红色名录中为自然保育而进行了评估 evaluated (VU) 易危（Vulnerable） (2006). Although the Mphanga Rock population is regularly fished for the aquarium hobby, I have not noticed a decline in population density over a period of about 20 years. The population density at Luwino Reef is much lower but these are not collected for the hobby or otherwise, and remains stable.
