Halymenia sp.

Halymenia , often simply referred to as "Red Algae", is a beautiful and versatile species of algae in the family Halymeniaceae. This algae is particularly known for its bright red to pink coloration and soft, flexible texture, which adds a vibrant and natural aesthetic to any saltwater aquarium.

The leaves of the Halymenia are thin, wavy and often semi-transparent, which gives them a fascinating glowing effect under aquarium light. The algae grows in bushy clumps and forms branched structures that can serve as hiding places for small fish and invertebrates.

Halymenia is not only an aesthetic eye-catcher, but also contributes to the biological balance in the aquarium by absorbing excess nutrients such as nitrates and phosphates.
