Rotala macrandra 'Mini Butterfly Hi Red'

Overview

Rotala macrandra 'Mini Butterfly Hi Red' is a highly prized red stem plant known for its intense crimson coloration, compact leaf size, and dense growth habit. It is a cultivated form of Rotala macrandra and is considered one of the most striking red plants used in modern aquascaping.

The "Hi Red" name is a trade designation rather than a formally recognized botanical variety. Different growers may maintain slightly different clones under the same name.

Appearance

Leaves

• Small, oval to rounded leaves.

• Much smaller than standard Rotala macrandra.

• Often slightly wavy or curled at the edges.

• Leaves grow in opposite pairs along the stem.

Color

Under ideal conditions:

• Deep crimson red

• Scarlet red

• Cherry red

• Ruby red

Under less favorable conditions:

• Orange-red

• Bronze-red

• Pinkish-red

• Greenish-red

The newest growth usually shows the strongest coloration.

Growth Habit

• Upright stem plant.

• Moderate growth rate.

• Naturally branches after trimming.

• Forms dense bushes when maintained regularly.

• More compact than standard Rotala macrandra.

Without pruning, stems tend to grow vertically and become less attractive.

Size

Typical dimensions under water:

• Height: 10–30 cm

• Width: 5–15 cm per clump

• Leaf size: approximately one-third to one-half the size of standard macrandra leaves

Suitable for:

• Midground in larger aquariums

• Background in nano tanks

• Transition zones between foreground and background

Difficulty

Advanced

This plant demands:

• Strong lighting

• Stable CO₂

• Consistent fertilization

• Good water quality

It is less forgiving than many common Rotala species and reacts quickly to instability.

Lighting Requirements

Best Results

High to very high light.

Strong lighting promotes:

• Deep red coloration

• Compact internodes

• Dense growth

• Healthy lower leaves

Insufficient light may cause:

• Green growth

• Long internodes

• Leaf drop

• Weak coloration

CO₂ Requirements

Pressurized CO₂ is strongly recommended.

Ideal conditions include:

• Stable CO₂ concentration throughout the day

• Good water circulation

• Minimal fluctuations

Poor CO₂ often leads to:

• Stunting

• Twisted growth

• Slow development

• Reduced coloration

Water Parameters

Preferred Range

• Temperature: 22–28°C

• pH: 5.5–7.0

• Soft to moderately soft water

• Low KH preferred

Soft water generally produces:

• Better color

• Faster growth

• Healthier leaves

Hard, alkaline water can make cultivation more difficult.

Nutrient Requirements

This is a relatively heavy feeder.

Macronutrients

Requires adequate:

• Nitrate (NO₃)

• Phosphate (PO₄)

• Potassium (K)

Micronutrients

Responds especially well to:

• Iron

• Trace elements

Balanced fertilization helps maintain:

• Strong red coloration

• Compact growth

• Healthy shoot tips

Substrate

Performs best in:

• Nutrient-rich aquasoil

• Mature planted aquariums

• Substrates with good nutrient reserves

Although it absorbs nutrients from the water column, a rich substrate often improves long-term performance.

Aquascaping Uses

Midground Accent

Most common placement.

Nano Background

Provides a dramatic red backdrop without becoming excessively large.

Dutch Aquascapes

Excellent for:

• Red plant streets

• Color contrast

• Focal groups

Nature Aquariums

Used as a striking accent among green plants.

Trimming

Regular trimming is important.

Recommended Method

1. Cut healthy tops.

2. Replant the tops.

3. Remove weak lower portions if necessary.

4. Allow side shoots to develop.

Benefits:

• Increased branching

• Denser bushes

• Better color

• More compact shape

Propagation

Simple stem propagation.

• Cut healthy stem tops.

• Replant cuttings.

• New shoots emerge from remaining nodes.

Once established, propagation is straightforward.

Common Problems

Comparison with Standard Rotala macrandra

Strengths

• Extremely intense red coloration.

• Compact growth suitable for smaller aquascapes.

• Creates dense, attractive bushes.

• Excellent contrast against green plants.

• Strong visual impact even in small groups.

• Highly valued by advanced aquascapers.

Weaknesses

• Demands stable CO₂.

• Requires strong lighting.

• Sensitive to water parameter swings.

• Not beginner-friendly.

• Can lose lower leaves if shaded.

• May stunt quickly when nutrients become imbalanced.

Ideal Setup

For the best results:

• Strong LED lighting

• Pressurized CO₂

• Nutrient-rich aquasoil

• Complete macro and micro fertilization

• Soft to moderately soft water

• Regular trimming and replanting

Quick Rating

Among red aquarium plants, Rotala macrandra 'Mini Butterfly Hi Red' is often considered one of the most vivid and compact choices available, capable of producing deep ruby-red bushes when grown under optimal conditions.
