Anubias Nana Mini Vs Petite – An Aquascaper’S Detailed Comparison

Written ByHoward Parker

Staring at two nearly identical tiny green plants, wondering which one is the perfect fit for your aquascape? You’re not alone, my friend. The choice between Anubias Nana Mini and Anubias Nana ‘Petite’ can feel surprisingly tricky, especially when they look so similar in the store.

I’ve been there, squinting at the leaves, trying to decide. But don’t worry, I’m here to clear up all the confusion for you. As someone who has grown, propagated, and aquascaped with both of these little gems for years, I promise to give you the straightforward, practical advice you need.

In this complete anubias nana mini vs petite guide, we’ll dive deep into their key differences in size, shape, and growth. We’ll explore the best ways to use them in your tank, cover a simple care routine to ensure they thrive, and even troubleshoot common problems. By the end, you’ll be able to choose with confidence, knowing exactly which tiny Anubias will bring your aquatic vision to life.

What’s in a Name? Unpacking the ‘Mini’ vs ‘Petite’ Confusion

First things first, let’s address the elephant in the room. Why is there so much confusion between these two plants? It’s because they are both tiny cultivars of the same parent plant, Anubias barteri var. nana. Think of them as siblings, not completely different species.

The ‘Petite’ variety, often sold as Anubias Nana ‘Petite’ or sometimes ‘Bonsai’, was originally cultivated from a unique mutation. Thanks to modern lab techniques like tissue culture, growers have been able to consistently reproduce this extra-small version, making it widely available.

Anubias Nana Mini is also a small variant, but it generally represents a slightly larger form than ‘Petite’. The key takeaway is this: while they share the same bulletproof hardiness and basic needs, their subtle differences in size and growth habit have a huge impact on how you’ll use them in an aquascape.

Anubias Nana Mini vs Petite: A Side-by-Side Visual Breakdown

Let’s get to the heart of the matter. When you put them side-by-side, the distinctions become clear. This is the core of the anubias nana mini vs petite debate, and understanding these physical traits will make your choice easy.

Leaf Size and Shape

The most immediate difference you’ll notice is the leaves. Anubias Nana ‘Petite’ has incredibly small, rounded leaves, often no bigger than your pinky fingernail (less than 1.5 cm). They grow very close together, giving the plant a dense, compact appearance that is perfect for intricate detail work.

Anubias Nana Mini, on the other hand, has leaves that are noticeably larger. They are often more elongated or spade-shaped and can easily reach 2-3 cm in length. While still a very small plant, it doesn’t have that same micro-level detail as ‘Petite’.

Growth Rate and Pattern

Anubias are famous for being slow growers, and these two are no exception. However, ‘Petite’ takes the prize for being one of the slowest-growing plants in the entire hobby. It sends out new leaves at a glacial pace, but the payoff is its growth pattern—it expands horizontally, creating a dense, low-profile mat over whatever surface it’s attached to.

Nana Mini grows slightly faster. You might see a new leaf every few weeks instead of every month or two. Its growth is also a bit more open and upright, resulting in a bushier, less compact clump over time.

Overall Plant Size and Stature

This is where your tank size comes into play. Anubias Nana ‘Petite’ is a true dwarf plant. It will rarely, if ever, exceed 2 inches (5 cm) in height. This makes it an absolute champion for nano tanks, betta bowls, and detailed foregrounds where every millimeter counts.

Anubias Nana Mini can reach a slightly more commanding height of up to 4 inches (10 cm). It’s still a small plant by any measure, but its larger stature makes it better suited for mid-ground areas, filling gaps in hardscape, or as a foreground plant in larger aquariums (20 gallons and up).

The Ultimate Anubias Nana Mini vs Petite Care Guide

Here’s the best news: caring for these plants is incredibly easy, and the requirements are virtually identical for both. If you’re looking for a forgiving plant, you’ve found it. This simple anubias nana mini vs petite care guide will ensure your success.

Lighting Requirements

Less is more! Both plants thrive in low to medium light. In fact, blasting them with high light is one of the biggest mistakes you can make. Because they grow so slowly, intense light just gives pesky algae a chance to grow on their leaves. Stick to a gentle light source, and your Anubias will thank you.

Water Parameters (pH, Temp, Hardness)

These plants are tough as nails and aren’t picky about water conditions. They are happy in a wide range of parameters, making them suitable for almost any community tank.

  • Temperature: 72-82°F (22-28°C)
  • pH: 6.0-8.0
  • Hardness: Soft to very hard water is tolerated well.

CO2 and Fertilization

You absolutely do not need CO2 injection for these plants to grow. They are perfectly content without it. However, adding CO2 can slightly speed up their slow growth rate.

For nutrients, they absorb what they need from the water column through their leaves and roots. Dosing a good quality, all-in-one liquid fertilizer once or twice a week is more than enough to keep them healthy and green.

The Golden Rule: Don’t Bury the Rhizome!

If you remember only one thing from this guide, let it be this. Anubias have a thick, horizontal stem called a rhizome where the leaves and roots sprout from. Never, ever bury this rhizome under your substrate.

Burying it will cut off its access to oxygen and cause it to quickly rot, killing the entire plant. This is one of the most common problems beginners face, but it’s so easy to avoid!

Aquascaping Like a Pro: How to Use Anubias Nana Mini vs Petite

Now for the fun part! Understanding how to anubias nana mini vs petite can elevate your aquascape from good to great. Here are some of the best practices I’ve learned over the years.

Best Uses for Anubias Nana ‘Petite’

Think small, think detail. ‘Petite’ is your go-to for:

  • Detailing Hardscape: Tucking tiny pieces into the cracks and crevices of driftwood or dragon stone.
  • Nano Tanks: It’s perfectly scaled for tanks under 10 gallons, where other plants would look oversized.
  • Creating Texture: Gluing several small pieces onto a rock can create a beautiful, textured focal point.

Best Uses for Anubias Nana Mini

Slightly larger, ‘Mini’ is a versatile workhorse for:

  • Mid-Ground Accents: Placing it at the base of larger hardscape elements to soften the transition to the substrate.
  • Filling Gaps: Its slightly bushier growth is perfect for filling in empty spaces between rocks or wood.
  • Foregrounds in Larger Tanks: In a 40-gallon tank, a clump of Nana Mini can serve the same role as ‘Petite’ does in a 5-gallon.

Step-by-Step Planting and Attachment Tips

Since you can’t bury the rhizome, you’ll need to attach your Anubias to a surface. It’s super simple!

  1. Prepare the Plant: Gently remove the plant from its pot and rinse away any rock wool or gel medium from the roots.
  2. Choose Your Method: You have two great options: super glue gel or cotton thread.
  3. The Super Glue Method (My Favorite): Pat the rhizome and the attachment spot on your rock or wood dry with a paper towel. Apply a tiny dab of super glue gel (make sure it’s 100% cyanoacrylate) to the rhizome and press it onto the surface for 30 seconds. You can place it back in the water immediately!
  4. The Thread Method: Simply use a dark-colored cotton thread to tie the rhizome securely to your hardscape. Don’t tie it so tight that you crush the rhizome. Over a few months, the plant’s roots will anchor themselves, and the cotton thread will naturally dissolve.

Troubleshooting Common Problems with Anubias Nana Mini vs Petite

Even the toughest plants can run into issues. Fortunately, the common problems with anubias nana mini vs petite are easy to diagnose and fix.

Battling Algae on Leaves

This is the number one issue. If you see green spot algae or black beard algae on the leaves, it’s almost always due to too much light. Reduce your lighting period to 6-8 hours a day or lower the intensity. A cleanup crew of Amano shrimp, nerite snails, or Otocinclus catfish can also be a massive help.

Yellowing Leaves (Chlorosis)

If new leaves are coming in pale or old leaves are turning yellow, it’s a sign of a nutrient deficiency. This is your plant’s way of saying, “I’m hungry!” Start dosing a comprehensive liquid fertilizer, and you should see the color improve in a few weeks.

Rhizome Rot

We’ve covered this, but it’s worth repeating. If you see a part of the rhizome turning black and mushy, it’s rotting. This can happen if it’s buried or damaged. Use a sharp, clean razor blade to trim away any affected parts. The healthy portion of the rhizome can often be saved.

Sustainable and Eco-Friendly Anubias Choices

In today’s hobby, making responsible choices matters. One of the best sustainable anubias nana mini vs petite practices is to opt for lab-grown, tissue-cultured plants whenever possible.

These plants are grown in a sterile gel medium, which means they are 100% free of pests, snails, and algae. When you buy a tissue culture cup, you know you’re not introducing any unwanted hitchhikers into your carefully balanced ecosystem.

This is an incredibly eco-friendly anubias nana mini vs petite option because it reduces the demand for wild-harvested plants and prevents the spread of invasive species. It’s a win for your aquarium and a win for the environment.

Frequently Asked Questions About Anubias Nana Mini vs Petite

Can Anubias Nana Mini and Petite grow floating?

Not really. While they won’t die immediately if they come loose and float, they will not thrive. Their roots need to attach to a surface to grow properly, so it’s always best to anchor them to hardscape.

Which is better for a betta tank?

Both are fantastic choices! Their sturdy leaves can handle a betta resting on them. For smaller betta tanks (5 gallons or less), Anubias Nana ‘Petite’ is probably the better choice due to its tiny scale. For a 10-gallon, either would work beautifully.

How fast do they actually grow? Can I speed it up?

Be patient! ‘Petite’ might only produce one new leaf per month, while ‘Mini’ might give you one every 2-3 weeks in good conditions. Adding CO2 and a regular fertilization schedule can encourage slightly faster growth, but they will never be “fast-growing” plants.

Do I need to trim these plants?

Very rarely. The only pruning you’ll need to do is to remove an old, yellowing leaf or to propagate the plant. To propagate, simply cut the rhizome with a clean blade, ensuring each piece has at least 3-4 healthy leaves.

So, Which Tiny Titan Will You Choose?

We’ve covered a lot of ground, from leaf size to aquascaping strategy. At the end of the day, the choice in the anubias nana mini vs petite showdown comes down to scale and purpose.

If you’re working on a nano tank, love intricate details, and want the smallest possible Anubias, then Anubias Nana ‘Petite’ is your undeniable champion. Its tiny, compact form is simply unmatched for fine detail work.

If you need a versatile, small-but-not-tiny plant to fill gaps in a larger tank or serve as a robust foreground accent, then Anubias Nana Mini is the perfect choice. It offers that classic Anubias look in a beautifully compact package.

No matter which you pick, you’re bringing home one of the hardiest, most rewarding plants in the aquarium hobby. They ask for very little but give so much in return, adding a touch of timeless green beauty to any underwater world. Now go forth and grow!
