General Description
The Green Finger Algae, scientifically known as Codium sp., belongs to the Codiaceae family and features striking green coloration with a bold architectural growth habit. It can grow up to 7.6cm in size and is considered a peaceful addition to marine aquariums. This ornamental macroalgae is reef-compatible and thrives in water conditions with a temperature tolerance of 20-27°C and specific gravity between 1.023-1.025.
Aquarium Suitability
The Green Finger Algae is well-suited for marine fish aquariums, mixed reef aquariums, refugiums, or seahorse systems. Its relative ease of care and aesthetic benefits make it a popular choice for aquarists looking to create visually appealing aquascapes that mimic natural marine environments.
Demands and Hardiness (see table)
Maintaining the Green Finger Algae in an aquarium requires moderate care. It benefits from supplements of magnesium, trace elements, and iron to support its growth. The algae thrives in water conditions with carbonate hardness of 8-12, pH value of 8.1-8.4, and moderate water flow. Light intensity can range from low to high, and it can tolerate nitrate levels between 5-50mg/l, phosphate levels of 0.1-3mg/l, and potassium levels of 1-30mg/l.
Aquascaping & Usage
When utilized in aquascaping, the Green Finger Algae adds a natural aesthetic to the aquarium, softening live rock and other decor to give the tank a mature and established look. Beyond its decorative appeal, this macroalgae provides water quality benefits through nutrient export and oxygenation, contributing to a cleaner and healthier aquatic environment. Interestingly, most herbivores tend to avoid feeding on the Green Finger Algae.
Propagation
Propagation of the Green Finger Algae can be achieved through fragmentation or spore release. Regular pruning can also help control its growth within the aquarium and prevent it from overtaking other tank inhabitants.
Habitat and Distribution
In its natural habitat, Codium sp. is often found in various marine environments, ranging from rocky coastlines to coral reefs. The species has a wide distribution in oceans around the world, where it plays a role in marine ecosystems by providing habitat for small invertebrates and contributing to nutrient cycling.
