The main characteristic of the Antennata Lionfish, Ragged-finned Firefish, or Spotfin Lionfish is the lack of connecting tissue in between the spines of the fin rays. The pectoral fins are connected only a short ways out from the body while the dorsal fins are not connected at all.
They do have venomous spines, our motto is "Don't pet the fish"!

Antennata Lionfish eating from a feeding stick.
Although the video quality is not perfect, this video needed to be chosen due to the wonderful training that was done for this Antennata Lionfish. All lionfish do need to be trained to eat from a feeding stick, since it is not always possible to have live foods and this aquarist did a great job. It is funny to watch the Lionfish respond to the stick even when it was on the outside of the tank! This Antennata Lionfish has found a good home and with proper feeding will reach 8" in no time. Remember do not feed goldfish to any marine fish.
The Antennata Lionfish, Ragged-finned Firefish, or Spotfin Lionfish is easy to keep. Lionfish are among the hardiest of all marine fish. In the beginning though, make sure you have a reliable supplier of feeder fish.
Feed live fish in the beginning, gradually enticing them to eat frozen of fresh foods such as silversides and lancefish. Other crustaceans and seafoods can also be tried.
