Lionfishincludes lionfish species
Lionfish are solitary creatures and quite popular with aquarists. Be careful handling lionfish, since their dorsal spines are venomous and can feel like a strong bee sting.
A well-balanced Lionfish diet consists of:
- Frozen food (silversides, krill, squid) and freezedried krill.
- May need to feed live food and transition over to frozen food or freezedried krill.
- Vary diet to ensure proper nutritional balance.
Things to remember when feeding your Lionfish:
- Feed 1 to 2 times a daily.
- If necessary, feed live fish in the beginning, gradually enticing them to eat other foods.
- Thaw frozen food before feeding.
- Keep in an appropriate size aquarium; provide rock and decor for hiding places and plenty of room for movement.
- Stable water quality, water temperature, and pH levels are critical to the health of the aquatic life. If you are unsure of your water quality or pH levels, Petco provides free water testing.
- Mostly solitary, not a very active swimmer.
- Lionfish attack their meal in one swift motion.
- Use caution: dorsal spines are venomous and can feel like a strong bee sting; although most people are not affected by lionfish stings, some humans may be allergic to the venom.
- Daily: Check filter, water temperature, specific gravity and other equipment.
- Weekly: Check water quality at least once a week.
- Monthly: Change 10 to 25% of the total volume of water every 2 to 4 weeks, or as needed.
