Larger crustaceans (Shrimp, crabs...)
This species is highly venomous and this venom can, under certain circumstances, be fatal.
In case of poisoning, it is vital to have as much information as possible regarding the species/poison. Have telephone number for the poison hotline close to the aquarium.
Since people can have different reactions to poisons, take precautions necessary to ensure your safety and that of your surroundings.
These fish often become tame over time and learn to recognize their owner.
This is problematic when working with ones hands in the tank, without the fish coming too close with its venomous spines.
These fish prefer live feed, such as live fish or shrimp. Some specimens refuse "dead" food altogether, while others can be trained to accept it.
Its easiest to move the frozen food around in front of the fish with a pair of tweezers. As soon as the fish shows interest and “attacks”, let go of the food.
They will try to eat all fish, shrimps and similar life forms that are small enough to fit in itheir mouth.
They should be fed a couple of times a week.
The fish and shrimps used as foods, must remain whole to give the Lionfish the optimum nutrition. The food must not be thawed naturaly, this helps to retain all the goodness.
Suitable live food are: Mollies, Guppies and Ghostshrimp. The feeder fish or shrimp should be fed with nutritious feed, like Cyclop-eeze for example.
This species thrives best in an aquarium with overhangs and caves.
Scorpion-/Lionfish (Scorpaenidae) are both pretty and interesting because of their special appearance and behaviour.
They are generally hardy and do not need a large swimming area, but do often require feeding with small live fish and/or shrimps. Some will quickly begin eating frozen fish or shrimp whilst others will refuse to eat "dead" food. Their food must be highly nutritious and varied. They must not be fed too often. Feed them a large meal twice a week.
These fish are mostly peaceful, but will eat anything that fits into their mouth. One might be surprised by how large their prey can be, they can even swallow fish which nearly match their own length. They will also eat each other, if the size difference is large enough. Their venomous spines do not guarantee that they will not be eaten by other predatory fishes.
Do be cautious when having your hands in the aquarium as these fish are very poisonous.
Some Scorpionfish require a special substrate, either coral gravel or fine sand, as this resembles their natural habitat.
Be careful when catching Scorpion-/Lionfish as they can easily get caught in the net.
|Distribution||Indo-Pacific: Red Sea to Sodwana Bay, South Africa and to the Society Islands, north to the Ryukyu Islands, south to New Caledonia. Records from the Mascarene Islands lack verification and are probably based on <i>Pterois antennata</i> (Ref. 33390).|

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
