Lionfish breed year-round. Females mature after turning one year old. After maturation, they produce about 50,000 eggs every three days for the rest of their lives. They reproduce much more quickly then the average reef fish that only spawns once a year. This can lead to an overpopulation of lionfish in reefs. Lionfish also have no natural predators which factors into the overpopulation also.
Diet of Lionfish
They are carnivores and eat once or twice a day depending on the fish. Lion fish enjoy small fish, invertebrates, and mollusks. They feed at dusk and dawn and have no need to chew their small prey. Occasionally, they will cannibalize smaller lionfish.
Typically, lionfish live anywhere from 10 to 16 years in the wild. Lionfish can live up to 18 years in captivity. It is important to keep this in mind when thinking of purchasing a lionfish.
Zebra Lionfish Tank
The water temperature should be kept between 72 and 78 degrees Fahrenheit. They should be kept in a tank that is at least 50 gallons, depending on the species. The water quality, temperature, and pH levels should be kept stable in order to keep your lionfish happy and healthy. The salinity level of the tank should be about 1.020 to 1.026. Rocks and decor should be provided for hiding places.
You should check the filter and water temperature daily. The water quality should be checked weekly. Every month, change 10 to 25% of the water. Be extra careful when performing maintenance to avoid getting stung.
Lion fish Tank Mates
New tank mates should be introduced gradually. Fish of similar or larger size make great tank mates for the lionfish, as they tend to eat fish smaller than themselves. Lionfish are most compatible with rock beauty angelfish, threadfin butterflyfish, Foxface rabbitfish, blue tang, maroon clownfish, snowflake moray eel, harlequin tusk fish, anglerfish, panther grouper, and the clown triggerfish.
They spend most of their time alone and are not overly active. They attack their meals quickly. Be cautious of their venomous dorsal spines. Their stings feel like a strong bee sting. Most are not affected by these stings, but it is possible to be allergic to them.
Lion fish originate from the South Pacific and Indian Oceans, including the Red Sea. Their tank temperature must stay in the 72 and 78F range because they are used to these warm, tropical waters in the wild.
