Ammannia gracilis Submersed Aquarium Plant – 5 Pack

Ammannia gracilis is a striking freshwater stem plant prized for its warm orange, pink and red foliage. This 5 pack is a great option for creating an instant group of colour through the midground or background of a planted aquarium.

The plants are supplied in their submersed-grown form, meaning they have already been growing underwater before sale. As live aquarium plants, stem length, size and colour will naturally vary depending on growth stage and the stock available at the time of your order.

Ammannia gracilis is best suited to aquarists with some planted-tank experience. It can grow under moderate conditions, but its best compact growth and orange-red to pink-red colour are achieved with good lighting, consistent nutrients and supplemental CO2.

Orange, Pink & Red Aquarium Colour

Ammannia gracilis is grown primarily for its attractive warm colour. Depending on aquarium conditions, the foliage can range from greenish-yellow and bronze through to orange, pink and deeper red tones.

Under moderate light the plant may remain greener or more orange, while stronger lighting combined with good nutrition and CO2 generally encourages more intense red and pink colouration.

A group of five plants creates a particularly effective contrast against green aquarium plants and works well as a feature planting in an aquascape.

Lighting Requirements

Ammannia gracilis performs best under medium to high aquarium lighting.

Under insufficient light, stems may become stretched and the plant can lose much of its characteristic warm colour.

Higher lighting should always be balanced with adequate nutrients and carbon availability. Simply increasing light without supporting healthy plant growth can encourage algae.

Does Ammannia gracilis Need CO2?

Ammannia gracilis can survive without injected CO2 in some aquariums, but CO2 is strongly recommended for its best growth, colour and overall appearance.

Controlled CO2 supplementation is particularly beneficial in higher-light planted aquariums and can help produce denser growth and stronger colour.

Fertilising Ammannia gracilis

Ammannia gracilis responds well to consistent access to macro and micronutrients.

A balanced aquarium plant fertiliser can help provide the nitrogen, phosphorus, potassium and trace elements required for healthy growth.

Red colour depends on the overall balance between lighting, nutrients, CO2 and plant health rather than one individual fertiliser ingredient.

Where to Plant Ammannia gracilis

Because Ammannia gracilis develops tall upright stems, it is generally best positioned in the midground to background.

With five plants supplied in this pack, you can create a grouped planting with strong visual impact.

For the best results, leave a small amount of space between individual stems rather than planting them tightly together. This allows better light penetration and water circulation around the lower leaves.

Trimming & Propagation

Ammannia gracilis is easily propagated from stem cuttings.

When stems become too tall:

1. Trim a healthy upper section using clean aquascaping scissors.
2. Remove leaves that would sit below the substrate.
3. Replant the cutting into the aquarium substrate.
4. Leave the original rooted section in place if it remains healthy.

The original stem can produce new side shoots below the cut, while the replanted top continues growing as a new plant.

Regular trimming and replanting can gradually turn the original five plants into a much larger, denser group.

Submersed-Grown Aquarium Plants

These Ammannia gracilis plants are supplied in submersed-grown form, meaning they have already been growing underwater.

Some adjustment can still occur after planting because lighting, nutrients, CO2 and water chemistry will differ between aquariums. Minor leaf loss during this adjustment period does not necessarily mean the plant has failed.

Fresh new growth at the tips of the stems is the best indication that the plants are adapting well.

Frequently Asked Questions

How many Ammannia gracilis plants are included?

This product contains five Ammannia gracilis plants or stems.

What size will the plants be?

Size and stem length naturally vary between shipments and individual live plants. We do not specify a fixed supplied height because growth can vary considerably.

Is Ammannia gracilis easy to grow?

It is best considered an intermediate aquarium plant. Good lighting, consistent nutrients and CO2 are recommended for compact growth and strong colour.

Does Ammannia gracilis need CO2?

CO2 is not absolutely essential for survival in every aquarium, but it is strongly recommended for the best growth, colour and overall appearance.

How tall does Ammannia gracilis grow?

It commonly reaches around 30–50cm in aquariums and can grow taller if it is not regularly trimmed.

Where should Ammannia gracilis be planted?

It is best suited to the midground or background because of its upright growth and eventual height.

How do I make Ammannia gracilis red?

Good aquarium lighting, adequate CO2 and balanced plant nutrition help encourage orange, pink and red colouration.

How do I propagate Ammannia gracilis?

Trim a healthy stem and replant the upper cutting into the substrate. The remaining rooted stem can also produce new side shoots.

What does submersed mean?

Submersed means the plants have been grown underwater before sale. Size, stem length, colour and growth form can still vary naturally.

Live aquarium plants naturally vary in size, colour and growth form. No fixed supplied height is guaranteed. Colour intensity depends on aquarium lighting, nutrients, CO2 and other growing conditions.
