Care

Rock Flower Anemones are relatively easy to care for, requiring moderate lighting and water flow. They do not have a symbiotic relationship with clownfish like other anemones, so they are less likely to wander in search of a partner. They can be fed a variety of meaty foods, such as mysis shrimp, finely chopped fish, and other prepared foods for carnivores.

Reproduction

In the home aquarium, Rock Flower Anemones can reproduce asexually by pedal laceration, where new anemones form from pieces of the parent's pedal disc. This can be a rewarding experience for the aquarist, as it allows for the propagation of the species within the tank.

Habitat

Phymanthus crucifer is found in the Caribbean Sea and the Western Atlantic, often nestled in rocky crevices or among rubble on the reef. They typically prefer lower light conditions in their natural habitat, which should be replicated in the home aquarium to some extent to encourage their best health and coloration.
