Typical appearance and behavior
- Foxface and rabbitfish are peaceful, but may be aggressive with another of their own species
- They are considered reef safe with caution when fed regularly; they may nip at large polyp stony corals or soft corals
- They will consume both nuisance algae and desirable algae
- Rabbitfish are known to control valonia algae
- They can be kept with larger and more aggressive fish due to their ability to defend themselves with their venomous spines

Habitat
Habitat size
Keep foxface and rabbitfish in an appropriately sized aquarium; a minimum of 75 gallons, depending on the adult size of the species, is recommended
Building your habitat
Water health:
- Provide proper filtration to ensure optimal water quality to help maintain health; moderate to strong water circulation will mimic water currents found in the foxface or rabbitfish’s natural habitat, depending on the species
- Stable water quality (pH, ammonia, nitrate, nitrite) and water temperature are critical to the health of aquatic life; if you are unsure of your water quality, bring a sample to Petco for free testing
- A protein skimmer can aid with maintaining great water quality and high dissolved oxygen levels
- Use an aquatic heater to stabilize water temperature, ensuring it does not fluctuate more than +/-2 degrees in a 24-hour period
- The specific gravity should remain stable; do not allow specific gravity to fluctuate more than +/-0.001 in a 24-hour period
Décor: Provide rocks and décor for hiding places and grazing as well as plenty of room for movement
Feeding
What to feed your foxface or rabbitfish
A well-balanced foxface or rabbitfish diet consists of:
- Commercial algae or algae sheets
- Marine flakes or pelleted herbivore foods
- Blanched lettuce or spinach
- Mysis shrimp and brine shrimp (frozen or freeze-dried)
Things to remember when feeding your foxface or rabbitfish:
- Algae or algae sheets should always be present in the aquarium (attach to the side of the aquarium with an algae clip)
- Feed other foods 2–3 times daily, no more than fish will eat in 1–2 minutes
- Thaw frozen food before feeding
Foxface and rabbitfish care
Water care: Maintaining great water quality with regular water changes and adequate filtration is important to help keep your foxface or rabbitfish healthy
