Care and Compatibility of Lionfish - Pterois volitans

Introduction

The lionfish, scientifically known as Pterois volitans or Pterois miles, is an invasive species native to the Indo-Pacific. It is characterized by its striped body, large pectoral fins, and venomous spines. Although it is a beautiful addition to the marine aquarium due to its exotic appearance, its introduction can have serious consequences for local ecosystems due to its predatory nature and ability to reproduce rapidly.

Behavior

The lionfish is a voracious predator that can be aggressive towards other fish and marine life in the aquarium. It has venomous spines on its dorsal fins that can cause painful injuries, so it should be handled with care. The lionfish tends to be unsociable even with other lionfish in an aquarium. They can tolerate the presence of other lionfish in the same tank, but they usually compete for territory and resources. In some cases, this competition can lead to aggression between lionfish, especially during feeding or if they feel threatened. Due to their territorial and aggressive nature, it is recommended to keep only one lionfish per tank unless the aquarium is large enough to provide multiple territories and hiding places. It's important to carefully consider the compatibility of tank mates before adding a lionfish to a community tank to avoid potential conflicts and injuries to other aquarium inhabitants.

Sexual Dimorphism

Sexual dimorphism in lionfish is not easily discernible to the naked eye. Both sexes have a similar appearance, although females may be slightly larger than males on some occasions.

Reproduction

Breeding lionfish in the aquarium is possible but can be difficult to control due to their prolific nature. They are broadcast spawners, releasing large quantities of eggs in a single spawning event. The eggs and larvae are pelagic and can be challenging to rear in captivity.

Aquarium Conditions

To keep a lionfish in the marine aquarium, a sufficiently large tank with ample hiding places and rocks to explore and hide is required. The water should be kept clean and well-oxygenated, with a temperature between 24°C and 27°C.

Feeding

The lionfish is an opportunistic predator that feeds on a variety of small fish, crustaceans, and other marine organisms. In the aquarium, it will accept a varied diet including shrimp, crabs, small fish, and frozen or live foods.

Complexity

The lionfish can be a challenging addition to the marine aquarium due to its predatory and venomous nature. It is recommended only for aquarists experienced in handling aggressive marine fish and understanding aquarium maintenance requirements.

No species is compatible with the Lionfish, however, 1 fish are semi compatible with the Lionfish with certain conditions special.
