Overview
The Possum Wrasse is a tiny, secretive fish with a pale-to-reddish body marked by fine dark banding and prominent black-edged fins, well suited to nano and small reef tanks where its diminutive size and quiet nature can shine. Unlike many other wrasses, it doesn't dive into the sand, instead retreating into small caves and crevices in the rockwork.
It's naturally shy and can take time to become confident in a new tank, often staying hidden for extended periods before venturing out to feed, particularly when first introduced.
Given a tank with plenty of small caves and crevices to explore, it's a peaceful, fully reef-safe addition that adds subtle activity low in the rockwork rather than open water.
Compatibility
Possum Wrasses are entirely peaceful and reef safe, posing no risk to corals or invertebrates. They can be shy around larger or more boisterous tankmates, so calm, non-aggressive fish give the best results.
They are generally unbothered by and unbothersome to other peaceful community fish, though their small size means they should not be kept with aggressive or predatory tankmates.
Health & quarantine
This species is generally hardy once settled, though it can take longer than many other wrasses to become confident and visible in a new tank. A standard quarantine period of two to four weeks is recommended good practice, and providing plenty of small caves and crevices from day one helps it settle more quickly.
