Cabomba caroliniana

Green Cabomba Growing & Care Guide

Green Cabomba is a classic background plant featuring delicate, fan-shaped whorled green leaves that create an incredibly dense, soft-textured underwater forest. Native to the Americas, this highly decorative stem plant is famous for absorbing excess water column nutrients and providing elite shelter for fish fry.

Lighting Moderate to High

Water Hardness Aquatic (pH 6.0-7.0)

Substrate Fine gravel or sand

Water Temp 15°C - 26°C

Toxicity Pet Friendly (Non-toxic)

How to Identify Green Cabomba

Green Cabomba (Cabomba caroliniana) has key botanical markers. Recognizing these features is crucial for successful aquascaping and thriving growth.

✔
Visual Shape & Growth: Stately vertical green stems dense with fan-shaped, finely-divided feathery leaves in neat whorls.
✔
Leaf Morphology: Exquisite, fan-like submersed leaves divided into fine, hair-like bright green segments.
✔
Root & Anchoring Structure: Fine, fibrous white root system growing from the lower nodes to anchor in sandy beds.

Complete Cultivation & Spawning Guide

Follow our detailed scientific water parameters and care guides to keep your Green Cabomba thriving.

pH: 6.0 - 7.0, GH: 3 - 8 dGH. Strongly prefers soft, slightly acidic to neutral water. Hard, alkaline water will stunt growth and rot stems.

Moderate. While it can grow without CO2 under moderate light, carbon injection promotes dense, compact whorls and prevents stem elongation.

Requires moderate to high lighting. Under low light, the stems become leggy, the whorl spacing widens, and lower leaves turn yellow and drop.

Clip top shoots and insert them into the substrate using aquascaping tweezers. Handle gently as the feathery stems are quite brittle.

Absorbs nutrients primarily through its delicate leaves from the water. Requires regular dosing of liquid micro-fertilizers, especially iron.

Prefers a fine gravel or sandy substrate. Plant the brittle stems deeply and gently to avoid crushing the lower node tissues.

Prefers cooler to moderate tropical temperatures between 15°C and 26°C (59°F - 79°F). Growth slows down dramatically above 28°C.

Requires moderate, clean water current. High flow will damage the delicate fan leaves, while stagnant water allows detritus to settle in the needles.

Perfect for small community fish and shrimps. Avoid large herbivorous fish like goldfish or aggressive cichlids, which will easily shred the soft leaves.

Its feathery needles are prone to catching hair algae. Keep nutrients balanced and use Amano shrimp or Nerite snails to maintain cleanliness.

Plant stems in groups of 3 to 5 in the background, spacing each stem slightly to ensure lower leaves receive adequate light.

Common Diseases & Treatment

Stem Melting (Hard Water Rot)

Symptoms: Stems turn soft, black, and dissolve from the bottom up, causing the plant to float away.

Action: Caused by hard water, high pH, or high temperatures. Move to soft water, trim the healthy tops, and replant.

Needle Shedding

Symptoms: The delicate green needles drop off in massive quantities, creating a messy tank.

Action: Indicates severe light starvation or chemical shock (such as copper treatments). Increase light and keep water clean.

Frequently Asked Questions

Why is my Cabomba losing all its leaves?

Cabomba sheds leaves when it doesn't receive enough light, is placed in hard water with high pH, or is exposed to fluctuating temperatures. Ensure soft water and strong lighting.

How do I plant Cabomba without crushing it?

Use fine-tip aquascaping tweezers to hold the stem gently at a lower node, push it straight down into sand or fine gravel, and release carefully.

Is Cabomba legal in the UK and Europe?

In some regions, Cabomba Caroliniana is classified as an invasive species and its trade is banned. Always check your local environmental laws before purchasing.

Does Cabomba need soil?

No, it does not require rich soil. It can grow perfectly well anchored in sand or fine gravel if liquid fertilizers are dosed weekly.
