White Banded Possum Wrasse

About this fish

White Banded Possum Wrasse is a small marine wrasse offered as Wetmorella tanakai. In a home aquarium, it’s primarily a display fish that helps bring motion to the rockwork, and it typically benefits from a well-structured aquascape where it can investigate surfaces and retreat into cover. Because wrasses are active and often show stronger feeding responses when they’re offered small meaty foods consistently, this fish is most practical for keepers who can maintain stable marine water conditions and feed appropriately.

Features:

• Active, rock-oriented swimming behavior that uses live rock and cover
• Best suited to aquariums with established filtration and stable, mature water conditions
• Carnivorous feeding style; generally responds well to small meaty foods
• Often benefits from aquascape that provides multiple hiding spots and sight breaks
• Usually more comfortable when introduced to a tank with available feeding opportunities and low stress
• A good option for experienced marine hobbyists comfortable with regular feeding and monitoring
