Common name: Sawblade Caulerpa

General information

Serrated Caulerpa (Caulerpa serrulata) is a species of green macroalgae commonly found in the marine aquarium trade. It is known for its attractive, feathery fronds and its ability to grow rapidly under the right conditions. This species is part of the Caulerpaceae family and is often used in refugiums to help control nutrients and reduce nitrates and phosphates in the aquarium.

Care

Caulerpa serrulata is relatively easy to maintain, making it a good choice for both novice and experienced aquarists. It requires moderate to high lighting and can benefit from the addition of trace elements and nutrients. Regular pruning is recommended to prevent it from overgrowing and potentially overtaking the tank. It's important to monitor its growth and ensure it doesn't spread to unwanted areas of the aquarium.

Symbiosis

While Caulerpa serrulata does not have any specific symbiotic relationships with fish or invertebrates, it provides a natural habitat and refuge for small organisms and can help create a more balanced and diverse ecosystem within the aquarium.

Habitat

In the wild, Caulerpa serrulata is found in shallow, tropical marine environments, often attached to rocks or coral rubble. It can be found in various regions including the Caribbean, the Indo-Pacific, and the Red Sea. In the aquarium, it should be anchored to a substrate or live rock to mimic its natural habitat.
