P. crucifer is a hardy specimen to keep in the aquarium and is appropriate for beginner aquarists. Due to its small adult size, it is suitable for the nano aquarium. It will obtain the energy it needs from its photosynthetic zooxanthellae, but will also appreciate supplemental meaty feedings (eg Mysis shrimp). Moderate-to-bright lighting, similar in appropriateness for soft corals, will support photosynthesis. Supplemental feeding will hasten growth and is particularly recommended if aiming for reproduction.
Compared to other sea anemones, P. crucifer has an extremely weak sting. It is not detectable by humans. P. crucifer tends to also be much more stationary than other sea anemones. Once they settle in a place they like in the aquarium (they might travel from where they are initially placed to find this spot), they tend to remain put. P. crucifer will not host anemonefish, but they will host a variety of invertebrates, such as sexy shrimp (Thor amboinensis), anemone shrimp (Periclimenes spp.), and porcelian crabs (Neopetrolisthes spp.)
