About the Foxface Rabbitfish
Foxface rabbitfish are active yellow algae grazers with a dark mask and a surprisingly large adult body. They need generous swimming room and should not be purchased as a temporary algae-control tool.
Their dorsal spines are venomous. Avoid direct handling, use a rigid container when moving the fish and make sure everyone maintaining the aquarium knows the risk.
Health risks to know about
Important concerns include venomous-spine injuries to people, marine parasites, poor nutrition, ammonia or nitrite poisoning, stress and wounds from territorial conflict.
Rapid breathing, repeated scratching, white spots, weight loss, damaged fins or refusing food needs prompt attention. A human sting needs immediate first-aid guidance and medical advice.
Tank, water and equipment
Use a large, long, mature marine aquarium with strong filtration, high oxygen, stable caves, open swimming lanes and a secure lid.
Measure salinity with a calibrated refractometer. Plan maintenance so hands do not need to pass close to the fish's dorsal spines.
Food and feeding
Offer marine algae sheets and a complete herbivore-focused food, with suitable marine animal foods for variety.
Feed enough plant matter for steady grazing without letting leftover sheets decay.
Behaviour, tank mates and enrichment
Active grazing is normal. When frightened or resting, a foxface may darken dramatically and wedge into cover with its spines raised.
Many are reef compatible with caution because a hungry individual may nip soft corals, fleshy LPS corals or clam mantles.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
