Info

Actinotrichia fragilis (Forsskål) Børgesen, 1932

The branches of this red alga are cylindrical and orange in color, regularly dichotomous with blunt tip sections.
Actinotrichia fragilis forms hemispherical clumps on rocks in the subtidal zones along the coasts where there is moderate to strong water movement.

Occasionally Actinotrichia fragilis appears commercially on a coral species, and its somewhat calcified structure rarely remains viable, yet with moderate water movement and balanced seawater parameters (calcium and alkalinity) it can be quite a handsome addition to the reef aquarium.

In addition, studies have shown that Actinotrichia fragilis in the form of dry powder or gel contain anti-inflammatory ingredients that can be used for osteoarthritis and are considered safe according to the OECD guideline.

Algae are valuable producers of oxygen.

Husbandry know-how of owners

Ich hatte eine ähnliche Alge im neu eingerichteten Aquarium, 1cm groß, weinrot, sehr schön ! wuchs auch sehr gut, war allerdings sehr zerbrechlich. Es brachen ständig Y förmige Teile ab. Überall wo diese liegen blieben wuchsen sie sofort an und weiter. Mit der Zeit war das ganze Aqarium voll mit dieser Alge ! Eine echte Plage !
