How The Turtle Got Its Shell – Your Ultimate Guide To Shell Dweller
Ever feel like you need a bigger tank to see truly fascinating fish behavior? You watch videos of intricate cichlid communities and think, “Maybe one day.” But what if I told you that you could witness complex social structures, territorial disputes, and dedicated parenting all within a 10-gallon tank on your desk?
It sounds too good to be true, but it’s the reality of keeping shell-dwelling cichlids. These tiny fish from Africa’s Lake Tanganyika have personalities ten times their size, and their entire world revolves around the empty snail shells they call home. For them, a shell isn’t just a house; it’s a castle, a nursery, and a safe haven.
Imagine creating a miniature, bustling city of these little aquatic architects right in your living room. In this guide, we’re going to unlock the secrets of how the turtle got its shell—our fun way of talking about creating the perfect environment for these amazing “shellies.”
Get ready to dive deep. We’ll cover everything from picking the perfect shells to designing their habitat and watching them thrive. Your journey to an incredible, small-scale cichlid world starts now!
What Are ‘Shellies’? Unpacking Our Aquarium ‘Turtles’
When we talk about our aquarium “turtles,” we’re referring to a special group of cichlids known as shell dwellers, or “shellies.” Hailing from the massive Lake Tanganyika in Africa, these fish have evolved a unique and captivating survival strategy: they live, breed, and raise their young exclusively inside empty snail shells scattered across the lakebed.
They are the ultimate homebodies! Unlike fish that hide in caves or among plants, shellies carry their protection with them, in a sense. Their shell is their territory, and they will defend it fiercely, arranging and burying it to their exact specifications.
Don’t let their small size fool you. Most shell dwellers are tiny, often maxing out at just 1-2 inches. But what they lack in size, they make up for in sheer personality and complex social behavior. They are constantly busy, digging, posturing, and interacting with their neighbors.
Meet the Popular Species
While there are many types of shell dwellers, a few have become superstars in the aquarium hobby. Don’t worry—these fish are perfect for beginners who are ready for a little cichlid attitude!
- Neolamprologus multifasciatus (‘Multies’): Often called the smallest cichlid in the world, ‘Multies’ are the quintessential shell dwellers. They form incredible colonies, with multiple generations living together in a dense city of shells. They are perhaps the best starting point for any aspiring shellie keeper.
- Neolamprologus similis: Slightly larger than Multies and with striking vertical bars that extend onto their fins, N. similis are another fantastic colony-forming species. They are known to be a bit bolder than Multies.
- Lamprologus ocellatus (‘Ocellatus’): The ‘Ocellatus’ or “Ocellated Shelldweller” is a true character. They are a bit more territorial and don’t form dense colonies like Multies, but their spunky, curious nature makes them a joy to watch. They come in several color variations, including ‘Gold’ and ‘Black’.
How the Turtle Got Its Shell Best Practices: The Shells Themselves
This is the most important part of our how the turtle got its shell guide. For these fish, the shells are everything. Getting this part right is the single biggest key to success. It’s not just about decoration; it’s about providing the fundamental building block of their environment.
Choosing the Right Shells
Not just any shell will do. You need to provide shells that are the right size and shape for your chosen species. The most popular and effective choice by far is empty escargot shells. You can buy these online or at specialty food stores (just be sure they are thoroughly cleaned and have no leftover oils or spices!).
- For Multies and Similis: Standard escargot shells with an opening of about 0.5 to 1 inch are perfect. They prefer the spiral, rounded shape.
- For Ocellatus: These fish have a slightly larger body, so they appreciate shells with a slightly wider opening, around 1 to 1.5 inches. Whale’s Eye or Magpie Turbo shells are also excellent options.
A great pro tip is to offer a variety of sizes. This allows the fish to choose their favorite and move into larger homes as they grow.
How Many Shells Do You Need?
Here’s a simple rule: always have more shells than fish. This is non-negotiable. Shells are property, and in the world of shell dwellers, property disputes can lead to stress and aggression. Providing an abundance of options diffuses tension.
A good starting point is at least 2-3 shells per fish. For a colony of 6 Multies, you should have a minimum of 15-20 shells scattered across the sand. More is always better! This surplus of real estate ensures everyone can find a home they love.
Preparing Shells for the Aquarium
You can’t just toss new shells into your tank. Proper preparation is crucial for the health of your fish. This is the core of how to how the turtle got its shell safely.
- Rinse Thoroughly: Start by rinsing the shells under hot tap water to remove any dust or debris.
- Boil Them: Place the shells in a pot of water and bring it to a rolling boil for 10-15 minutes. This sterilizes them, killing any harmful bacteria or organisms.
- Cool Down: Carefully remove the shells from the pot (they will be extremely hot!) and let them cool down completely to room temperature.
- Final Rinse: Give them one last rinse in some dechlorinated water before adding them to your aquarium.
Building the Perfect Shell Dweller Habitat: A Step-by-Step Guide
Now that we have our shells, it’s time to build the world around them. Creating the right environment is surprisingly simple, but a few key details make all the difference. This section covers the best practices for a thriving, sustainable how the turtle got its shell setup.
Tank Size and Setup
One of the greatest benefits of keeping shellies is that they are perfect for smaller tanks. A 10-gallon tank is a great starting point for a small colony of N. multifasciatus. For a species like L. ocellatus or for a larger colony, a 20-gallon long provides more floor space for territories.
The tank’s footprint (length and width) is far more important than its height. These are bottom-dwelling fish, so give them as much ground to cover as possible!
The Ideal Substrate: Sand is a Must
If shells are the #1 requirement, a fine sand substrate is a very close #2. Shell dwellers are prolific diggers. They will excavate pits, bury their shells completely, create barricades, and constantly re-landscape their territory. It’s one of their most endearing behaviors!
Use a fine-grain aquarium sand, like pool filter sand or CaribSea Super Naturals. Aim for a sand bed that is at least 1.5 to 2 inches deep. This gives them plenty of material to work with. Gravel is not suitable as it prevents them from digging and can even injure them.
Water Parameters and Filtration
Shell dwellers come from Lake Tanganyika, which has very specific water chemistry. It’s hard, alkaline, and warm. Replicating this is key to their long-term health.
- Temperature: 76-80°F (24-27°C)
- pH: 8.0 – 9.0
- Hardness (GH/KH): Very hard water is preferred, around 10-20 dGH.
If your tap water is soft, you can use crushed coral or aragonite sand as a substrate to help buffer the pH and hardness. For filtration, a simple sponge filter or a hang-on-back filter with a low flow rate is perfect. You don’t want strong currents blowing them and their sand around.
Aquascaping and Tank Mates
While the shells are the main event, adding a few rocks can help create visual barriers and define territories. This is especially helpful in breaking up lines of sight and reducing aggression.
As for tank mates, a species-only tank is often the most rewarding, as it allows their natural behaviors to shine. If you do want tank mates, choose fish that occupy the upper levels of the tank and can handle the hard, alkaline water. Cyprichromis or Paracyprichromis species (featherfins) are a classic and excellent choice.
Common Problems with How the Turtle Got Its Shell (And How to Solve Them!)
Even in the best setups, you might run into a few bumps. Don’t worry! Here are some common problems and straightforward solutions. Think of this as your troubleshooting how the turtle got its shell care guide.
Aggression and Territorial Disputes
Problem: You notice fish chasing each other relentlessly or fighting over a specific area.
Solution: This is almost always a real estate issue. The first step is to add more shells. Spreading them out across the tank can also help. Secondly, use rocks to create visual barriers so a dominant fish can’t see and control the entire tank from one spot.
Fish Not Using the Shells
Problem: You’ve provided beautiful shells, but your fish are ignoring them and hiding in corners.
Solution: Give them time! New fish can be shy. Ensure the shells are the right size—if the opening is too small or too large, they won’t feel secure. Also, check for bullies. If a more dominant fish (or an unsuitable tank mate) is terrorizing them, they won’t feel safe enough to claim a home.
Uncontrolled Breeding
Problem: Your Multies have started a colony… and it’s not stopping! Your tank is getting crowded.
Solution: This is a sign of a happy, healthy environment! The easiest way to manage the population is to simply stop intervening. In a mature colony, the population will often self-regulate based on available space and resources. If you need to thin the herd, you can often sell or trade the fry with other hobbyists or your local fish store.

- You Get to Be a City Planner: You provide the building blocks (the shells), and they build the city. Watching a colony grow and develop is an unparalleled experience.
Frequently Asked Questions About How the Turtle Got Its Shell
What are the best shells for Multifasciatus cichlids?
The hands-down best choice is escargot shells. The size, shape, and weight are perfect for them. Look for shells with an opening of about 3/4 of an inch. Neothauma snail shells from Lake Tanganyika are the “natural” choice but are much harder to find and more expensive.
Can I keep shell dwellers with community fish like tetras or guppies?
It’s generally not recommended. The primary issue is water parameters. Shell dwellers require very hard, alkaline water (high pH), while most common community fish prefer softer, more acidic water. Keeping them together means one group will always be stressed and unhealthy.
How often should I feed my shell dwellers?
They are not picky eaters. A high-quality micropellet or crushed flake food should be their staple diet. Feed a small amount once a day. You can supplement their diet with frozen foods like baby brine shrimp or daphnia a few times a week as a treat.
Why are my shell dwellers burying their shells?
This is completely normal and a sign they are comfortable! They do this for security and to position the shell opening exactly where they want it. Sometimes they will bury it completely, leaving only a small opening visible. It’s fascinating behavior to watch.
