Callitriche terrestris

Species description

Care, breeding and tankmates

Plant profile

Placement

Foreground

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

Stem

The Callitriche terrestris 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

Fast

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

Medium

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

Nano, Midground, Foreground, group

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.
