Anubias nana sp. is a popular and relatively easy-to-care-for aquarium plant, known for its compact size, slow growth, and hardiness. It's a variant of the Anubias barteri species and is highly appreciated in the aquascaping world for its attractive dark green leaves and versatility. The "sp." simply indicates that it’s a specific variety or subspecies, often characterized by slightly different appearance or origins, but its care needs are virtually the same as the classic Anubias nana.
Here’s a care guide for Anubias nana sp.:
Low to Moderate Light: Like all Anubias species, Anubias nana sp. does best under low to moderate lighting. It can tolerate low light and will grow slowly, but if placed under strong, direct light, algae may start to build up on the leaves.
Lighting Setup: A lighting intensity of 2-3 watts per gallon is ideal for promoting slow, steady growth without encouraging excessive algae. LED or fluorescent lighting works well for this plant.
Ideal Temperature Range: Anubias nana sp. thrives in tropical temperatures, typically between 72°F to 82°F (22°C to 28°C). It is adaptable to a range of temperatures within this bracket and can tolerate slight fluctuations in temperature, though extreme changes should be avoided.
pH: This plant prefers slightly acidic to neutral pH levels, ranging from 6.5 to 7.5. It can tolerate a wider pH range, but keeping it within this optimal range will support healthy growth.
Water Hardness: Anubias nana sp. is adaptable to a variety of water hardness levels, from soft to moderately hard water (3-8 dGH). It will do well in most water conditions.
Water Flow: Anubias nana sp. prefers low to moderate water flow. It’s important to avoid strong currents, as these can damage the plant and stress it out. Ensure it is not placed near strong filter outflows or high-water-movement areas.
Rhizome-Based Growth: Like all Anubias varieties, nana sp. grows from a rhizome. The rhizome should never be buried in the substrate, as this can lead to rot. Instead, attach the rhizome to rocks, driftwood, or other hard surfaces using aquarium-safe glue or fishing line.
Substrate Type: You can use gravel, sand, or nutrient-rich substrate. Although Anubias nana sp. doesn’t absorb nutrients through its roots, a nutrient-rich substrate may help its overall health and provide a natural environment. However, substrate choice is not crucial as the plant takes up nutrients mainly through its leaves.
Liquid Fertilizer: While Anubias nana sp. is not a heavy feeder, it can benefit from occasional liquid fertilization. Use a balanced liquid fertilizer with micronutrients, especially if your tank water is low in nutrients. It’s recommended to fertilize once every 1-2 weeks for optimal growth.
CO₂: Adding CO₂ can boost growth and health, but it’s not essential for Anubias nana sp. It will grow just fine without CO₂ supplementation, making it a good plant for low-tech setups.
Slow Grower: Anubias nana sp. is a slow-growing plant, so it doesn’t need frequent pruning. However, you should remove any dead or damaged leaves to keep the plant looking clean and healthy.
Algae Growth: Like many Anubias species, nana sp. can develop algae on its leaves, especially in tanks with high light. To reduce algae buildup, clean the leaves with a soft sponge or toothbrush. Adding algae-eating species like otocinclus catfish or shrimp (like Amano shrimp) can help control algae naturally.
Community Tank Friendly: Nana sp. is a peaceful plant and can be kept with a wide variety of peaceful fish and shrimp species. It’s particularly well-suited to community tanks, as it’s unlikely to be eaten or damaged by most fish.
Avoid Plant-Eating Fish: While most fish won’t bother Anubias nana sp., it’s best to avoid aggressive or plant-eating species like goldfish, large cichlids, or certain herbivorous fish (e.g., some types of plecos or larger catfish).
Compact Growth: Nana sp. typically reaches a height of around 3-5 inches (8-12 cm), making it a small to medium-sized plant. It’s perfect for foreground or midground placements in aquariums, especially nano or small tanks.
Slow Growth: Like all Anubias plants, it’s a slow grower, making it ideal for aquarists who prefer low-maintenance plants that don’t require constant attention or trimming.
Yellowing Leaves: This can be a sign of a nutrient deficiency, especially if the plant is not getting enough iron or nitrogen. Consider adding a liquid fertilizer with micronutrients if the leaves begin to yellow.
Rhizome Rot: If the rhizome is buried in the substrate or exposed to poor water conditions (e.g., poor circulation), it may begin to rot. Ensure the rhizome is always exposed to water and is not buried in the substrate.
Algae Buildup: If algae starts to accumulate on the leaves, reduce lighting intensity or move the plant to a lower light area of the tank. Algae-eating fish or snails can help keep the plant clean.
Aquascaping with Anubias nana sp.: The compact size and attractive dark green leaves make nana sp. an excellent choice for aquascaping. It can be placed on driftwood or rocks to create beautiful, natural-looking setups. Its dark, rounded leaves contrast nicely with finer-leaved plants or mosses.
Light: Low to moderate
Temperature: 72-82°F (22-28°C)
pH: 6.5 to 7.5 (slightly acidic to neutral)
Water Flow: Low to moderate
Fertilization: Light fertilization with liquid nutrients (balanced with micronutrients)
Substrate: Attach to rocks or driftwood (avoid burying rhizome)
Pruning: Remove dead or damaged leaves as needed
Tankmates: Peaceful species (shrimp, small tetras, peaceful fish)
With these care tips, your Anubias nana sp. will thrive and add a lush, elegant touch to your aquarium. It’s a fantastic, low-maintenance plant that can be enjoyed by aquarists of all experience levels.
