General Description
Caloglossa cf. beccarii is a visually striking red alga with ramified thalli that feature leaf-like lanceolate fronds in brown, dark purple, or greyish green colors. It is known for forming moss-like tufts or tangled clumps and attaching itself to tank decorations, plants, or mosses with the help of its rhizoids. Belonging to the Delesseriaceae family, this alga is closely related to marine red algae and is commonly found in warmer regions in sea, brackish waters, and freshwater streams.
Aquarium Suitability
Caloglossa cf. beccarii is considered suitable for aquariums, although it can become problematic due to its propensity to grow in tufts or between slow-growing epiphytes. Removal can be challenging as parts of the thalli and rhizoids often remain, leading to regrowth. Its low light requirements make it thrive in dark corners and densely planted tanks, sometimes requiring a complete reset to eradicate it effectively.
Demands and Hardiness
For optimal growth, Caloglossa cf. beccarii thrives in a pH range of 5-9, with a temperature tolerance between 18-30°C. It can adapt to a wide range of lighting conditions, from low to high, and requires a carbon dioxide (CO2) concentration of 0-40mg/l. The alga's tolerance levels for carbonate hardness, iron (Fe), nitrate (NO3), phosphate (PO4), and potassium (K+) are within specific limits.
Aquascaping & Usage
In aquascaping, Caloglossa cf. beccarii can add unique texture and color to freshwater tanks. Its moss-like tufts and branching patterns contribute to a natural look, especially when used strategically in shaded areas or as an accent plant. However, its invasive growth nature requires careful planning to prevent overgrowth and spread.
Propagation
Propagation of Caloglossa cf. beccarii is typically achieved through splitting and cutting off daughter plants. This method allows for the creation of new clusters of the alga for expansion or maintenance within the aquarium.
Habitat and Distribution
Natively found in warmer regions of the world, Caloglossa species, including Caloglossa cf. beccarii, can be observed in river mouths where they grow epiphytic on mangrove roots. Their adaptability to various aquatic environments, from freshwater streams to sea habitats, showcases their versatile distribution and habitat preferences.
