Species description

Distributed in brackish and fresh waters of tropical and subtropical areas, particularly in Southeast Asia and Oceania. It grows anchored to rocks, mangrove roots, and riverbanks in shaded areas with constant water flow. It is a red alga (Rhodophyta) belonging to the Delesseriaceae family. The designation 'cf.' (confer) suggests its affinity with the species beccarii, although the freshwater populations kept in aquaria show stable genetic traits not yet fully classified. Lacks true stems or leaves, having a flat, dichotomously branched (divided in two) thallus that forms dense cushions.

Care, breeding and tankmates

Tolerant of a wide spectrum of water hardness (KH 2-21) and pH (5.0-9.0). Thrives in temperatures between 18 and 30°C. It also adapts to brackish water, showing extraordinary resilience. Not subject to common diseases of higher plants. The main risk is that it detaches from the hardscape and ends up in the filter, or that it gets smothered by organic debris if the water flow is poor.

Geographic Origin and Distribution

This species originates from: Tropical and subtropical regions, Southeast Asia, Oceania.

Plant profile

Placement
Epiphyte

Suitable for various positions depending on the aquascape design, usually midground or background. Its unique texture adds visual interest and contrast when grouped with other species. Make sure it has enough room to grow without being entirely shaded.

Botanical form
Algae

The Caloglossa cf. beccarii exhibits a distinctive morphological structure that stands out in planted tanks. Its leaf shape and stem arrangement make it highly recognizable. Under good light, its colors become more pronounced and vibrant.

Growth
Medium

Grows at a moderate to fast rate depending on the light and CO2 levels available. In high-tech tanks, it may require frequent trimming to keep it in shape. In low-tech setups, it will grow much slower but remain healthy.

Substrate
None
Column fertilization
Recommended

Absorbs most of its required nutrients directly from the water column. Liquid fertilizers are highly effective and should be dosed regularly. Keeping a consistent nutrient level is key to avoiding deficiency symptoms.

Root fertilization
None

While it can survive without it, a nutrient-rich substrate can offer a good backup nutrient source. Root tabs are beneficial if the substrate is old or inert. However, water column dosing should remain the primary focus.

Trimming
Occasional

Trimming is straightforward; simply cut the stems or leaves to the desired length. Regular pruning encourages bushier, denser growth and prevents the plant from taking over the tank. Replant the healthy trimmings if you wish to expand its footprint.

Propagation
Cuttings

Propagation is very simple by dividing the plant or replanting cuttings. The cuttings quickly develop roots and establish themselves in the substrate. Ensure the new cuttings receive adequate light to encourage fast rooting.

Sensitivity
Moderate

Generally robust but can melt if water parameters swing drastically. It prefers stable conditions and clean water with good flow. Algae can be an issue if organic waste is allowed to accumulate on its delicate leaves.

Layout role
Foreground, Midground, Epiphyte

Excellent for creating natural-looking thickets or adding a touch of wildness to the aquascape. It bridges the gap between different plant groups beautifully. Its unique texture provides a great contrast to broad-leaved plants.
