$6.75
Natural Great Lakes stone plant anchors for aquariums. Fish-safe, lead-free, and non-toxic. Keep live plants grounded with eco-friendly beauty.
🌱 Secure Your Live Aquarium Plants — Naturally & Beautifully
Tired of floating plants and constant replanting? Our natural stone aquarium plant anchors offer a safe, effective, and visually pleasing solution. Handcrafted from smooth, wave-worn Lake Michigan and Lake Superior stones, these plant weights blend seamlessly into your aquascape—adding beauty while keeping your plants firmly in place.
Unlike mass-produced overseas river rocks and lead bands, these chemical-free, fish-safe, and non-toxic stones are a healthy alternative for your freshwater tank. Each piece is unique, shaped by nature, and completely safe for all aquatic life.
Whether you're building a low-tech setup or a lush, high-tech aquascape, these anchors work great for stem plants, rooted plants, and floating species that need a little help staying grounded. They’re especially helpful in tanks with diggers like cichlids, plecos, gouramis, corydoras, loaches, oscars, and crustaceans, who are known for uprooting even the most determined plants.
🪴 Say goodbye to constant maintenance—and enjoy a more stable, natural-looking underwater world.
📦 Shipping & Savings
When purchasing three or more stones, or stones in different sizes and types, you’ll typically receive a partial shipping refund.
Most bundled orders ship for $6.00 to $9.00, and any overage over $1.00 will be refunded—so you can shop confidently knowing you won’t be overcharged.
💡 The more you bundle, the more you save!
🪨 Stone Colors & Custom Options
Each anchor stone is naturally one-of-a-kind, with unique patterns, textures, and tones shaped by time and freshwater waves. While listing photos reflect the general style, no two stones are exactly alike, making each one a natural addition to your aquascape.

Privacy policy
Etsy Seller: Michael Wilson, Michael’s Privacy Policy
This Privacy Policy describes how and when I collect, use, and share information when you purchase an item from me, contact me, or otherwise use my services through Etsy.com or its related sites and services.
This Privacy Policy does not apply to the practices of third parties that I do not own or control, including Etsy or any third party services you access through Etsy. You can reference the Etsy Privacy Policy to learn more about its privacy practices. Nathan should then go on to include information on the following:
Information I Collect
To fulfil your order, you must provide me with certain information (which you authorized Etsy to provide to me), such as your name, email address, postal address, payment information, and the details of the product that you’re ordering. You may also choose to provide me with additional personal information (for a custom order of jewelry, for example), if you contact me directly.
Why I Need Your Information and How I Use It
I rely on a number of legal bases to collect, use, and share your information, including:
• as needed to provide my services, such as when I use your information to fulfil your order, to settle disputes, or to provide customer support;
• when you have provided your affirmative consent, which you may revoke at any time, such as by signing up for my mailing list;
• if necessary to comply with a legal obligation or court order or in connection with a legal claim, such as retaining information about your purchases if required by tax law; and
• as necessary for the purpose of my legitimate interests, if those legitimate interests are not overridden by your rights or interests, such as 1) providing and improving my services. I use your information to provide the services you requested and in my legitimate interest to improve my services; and 2) Compliance with the Etsy Seller Policy and Terms of Use. I use your information as necessary to comply with my obligations under the Etsy Seller Policy and Terms of Use.
Information Sharing and Disclosure
Information about my customers is important to my business. I share your personal information for very limited reasons and in limited circumstances, as follows:
• Etsy. I share information with Etsy as necessary to provide you my services and comply with my obligations under both the Etsy Seller Policy and Etsy Terms of Use.
• Service providers. I engage certain trusted third parties to perform functions and provide services to my shop, such as delivery companies. I will share your personal information with these third parties, but only to the extent necessary to perform these services.
• Business transfers. If I sell or merge my business, I may disclose your information as part of that transaction, only to the extent permitted by law.
• Compliance with laws. I may collect, use, retain, and share your information if I have a good faith belief that it is reasonably necessary to: (a) respond to legal process or to government requests; (b) enforce my agreements, terms and policies; (c) prevent, investigate, and address fraud and other illegal activity, security, or technical issues; or (d) protect the rights, property, and safety of my customers, or others.
Data Retention
I retain your personal information only for as long as necessary to provide you with my services and as described in my Privacy Policy. However, I may also be required to retain this information to comply with my legal and regulatory obligations, to resolve disputes, and to enforce my agreements. I generally keep your data for the following time period: 4 years.
Transfers of Personal Information Outside the EU
I may store and process your information through third-party hosting services in the US and other jurisdictions. As a result, I may transfer your personal information to a jurisdiction with different data protection and government surveillance laws than your jurisdiction. If I am deemed to transfer information about you outside of the EU, I rely on Privacy Shield as the legal basis for the transfer, as Google Cloud is Privacy Shield certified.
Your Rights
If you reside in certain territories, including the EU, you have a number of rights in relation to your personal information. While some of these rights apply generally, certain rights apply only in certain limited cases. I describe these rights below:
• Access. You may have the right to access and receive a copy of the personal information I hold about you by contacting me using the contact information below.
• Change, restrict, delete. You may also have rights to change, restrict my use of, or delete your personal information. Absent exceptional circumstances (like where I am required to store data for legal reasons) I will generally delete your personal information upon request.
• Object. You can object to (i) my processing of some of your information based on my legitimate interests and (ii) receiving marketing messages from me after providing your express consent to receive them. In such cases, I will delete your personal information unless I have compelling and legitimate grounds to continue using that information or if it is needed for legal reasons.
• Complain. If you reside in the EU and wish to raise a concern about my use of your information (and without prejudice to any other rights you may have), you have the right to do so with your local data protection authority.
