Fish That Eat Malaysian Trumpet Snails – Your Ultimate Guide

Written ByHoward Parker

Let’s be honest, we’ve all been there. You spot one tiny, cone-shaped snail on your aquarium glass. You think, “Oh, how cute!” A week later, you see ten. A month later, your substrate seems to be moving on its own, and you realize you have a full-blown Malaysian Trumpet Snail (MTS) population explosion.

It’s a classic story in the aquarium hobby, and it can feel overwhelming. You start wondering if you’ll ever see your beautiful gravel again. I promise you, there is a natural, effective, and fascinating solution that doesn’t involve chemicals or tearing your tank apart.

In this guide, I’m going to walk you through everything you need to know about the best fish that eat malaysian trumpet snails. We’ll explore which fish are the hungriest snail predators, how to choose the perfect one for your specific tank, and how to care for them to create a healthy, balanced ecosystem. Let’s turn that snail problem into a thriving aquatic community!

First, Are Malaysian Trumpet Snails Really a Problem?

Before we declare all-out war, it’s important to understand your tiny tenants. Malaysian Trumpet Snails, or MTS, aren’t pure villains. In fact, in small numbers, they are a fantastic part of your tank’s cleanup crew.

They burrow through the substrate, which helps aerate it and prevent dangerous pockets of anaerobic gas from building up. They also munch on leftover fish food and decaying plant matter, keeping your tank cleaner. The problem isn’t their existence; it’s their overpopulation.

A sudden explosion of MTS is almost always a sign of one thing: overfeeding. These snails are opportunistic breeders. When there’s a constant buffet of uneaten food, they reproduce at an incredible rate. So, while we look for fish to help, remember that reducing how much you feed is the first and most important step.

The Top 5 Fish That Eat Malaysian Trumpet Snails

Alright, you’ve cut back on feeding, but you still need some help with the existing snail army. Let’s bring in the cavalry! Here are my top picks for fish that absolutely love to snack on MTS. This complete fish that eat malaysian trumpet snails guide will help you make the right choice.

1. The Loach Family: Nature’s Snail Vacuums

When it comes to snail control, loaches are the undisputed champions. They have specialized mouths perfect for slurping snails right out of their shells. But not all loaches are created equal!

  • Clown Loach (Chromobotia macracanthus): The most famous snail-eater. They are incredibly effective and fun to watch. However—and this is a big one—they get huge (up to 12 inches) and need to be in groups of 5+. A single Clown Loach in a small tank is not a sustainable or humane solution. They are only suitable for tanks of 125 gallons or more.
  • Yoyo Loach (Botia almorhae): A fantastic alternative for medium-sized tanks (40+ gallons). They are active, curious, and have a huge appetite for snails. Keep them in groups of at least 5-6 to see their best, most playful behavior.
  • Zebra Loach (Botia striata): Smaller and more peaceful than many of their cousins, Zebra Loaches are perfect for community tanks of 30 gallons or more. They are relentless snail hunters and do best in groups.
  • Dwarf Chain Loach (Ambastaia sidthimunki): My personal favorite for smaller tanks! These little guys are peaceful, stay small (around 2.5 inches), and are perfect for 20-gallon tanks and up. A group of them will diligently clean your substrate without bothering most other fish.

2. Pufferfish: The Specialist Assassins

If you want a fish whose entire life revolves around crunching shells, look no further than puffers. Their beaks are designed for it! But they come with a very specific set of requirements.

  • Pea Puffer (Carinotetraodon travancoricus): Also known as the Dwarf Puffer, these tiny fish are adorable but fierce predators. They will systematically destroy a snail population. However, they are not community fish. They are aggressive fin-nippers and are best kept in a species-only tank. They also require a steady diet of snails or other hard-shelled foods to keep their beaks trimmed.
  • Amazon Puffer (Colomesus asellus): A larger, freshwater puffer that can sometimes be kept in a carefully planned community tank. They are less aggressive than Pea Puffers but still need a diet rich in snails to stay healthy.

3. Gouramis: The Surprising Contenders

While not their primary food source, some species of Gourami will happily pick off smaller MTS, especially the young ones. They are a good option if you have a mild snail problem and want a beautiful centerpiece fish.

  • Sparkling Gourami (Trichopsis pumila): These nano fish are perfect for smaller tanks. In addition to their beauty, they are known to hunt and eat baby snails and other small invertebrates.
  • Dwarf Gourami (Trichogaster lalius): Many keepers report their Dwarf Gouramis actively hunting small snails. It can be hit-or-miss depending on the individual fish’s personality, but they can certainly help keep numbers in check.

4. Bettas (Betta splendens)

Don’t overlook the humble Betta! Many Bettas have a strong predatory instinct and will readily hunt down and eat small snails. It’s a great form of enrichment for them. Just be sure the snails are small enough for them to eat safely.

5. Corydoras Catfish (Some Species)

This is a bit of a bonus and not a primary solution. While most Corydoras won’t eat adult snails, some larger species like the Corydoras aeneus have been observed crushing and eating very small, young snails they find while sifting through the substrate. They are more of a preventative measure than a cure.

How to Choose the Right Snail-Eating Fish for Your Aquarium

Picking a fish just because it eats snails is a recipe for disaster. You need to choose one that fits your specific setup. Here’s a quick checklist to guide you through the process of how to fish that eat malaysian trumpet snails correctly.

Step 1: Consider Your Tank Size

This is non-negotiable. Don’t put a Clown Loach in a 20-gallon tank expecting it to be fine. Always research the adult size of a fish before you buy it. A happy fish is an effective fish, and a cramped fish is a stressed and unhealthy one.

Step 2: Check Your Water Parameters

Make sure your tank’s pH, temperature, and hardness match the needs of your chosen snail-eater. Most loaches, for example, prefer slightly softer, acidic water, though many are adaptable.

Step 3: Evaluate Tank Mate Compatibility

Who else lives in your tank? If you have delicate shrimp or long-finned fish like guppies, a Pea Puffer is a terrible idea. Peaceful Dwarf Chain Loaches, on the other hand, would be a much better fit. Always think about the entire community.

Step 4: Understand Their Social Needs

Many of the best snail-eaters, especially loaches, are social fish that need to be in groups. Keeping them solo will cause stress, hiding, and can even lead to aggression. A proper school will make them feel secure and more effective at their job.

A Complete Fish That Eat Malaysian Trumpet Snails Care Guide

Bringing home your new snail-eating crew is just the beginning. Proper care ensures they stay healthy and effective. This is a core part of our fish that eat malaysian trumpet snails care guide.

The Importance of a Balanced Diet

Snails should be a treat, not the entire meal. Your snail-eating fish need a varied, high-quality diet. This is one of the most important fish that eat malaysian trumpet snails tips I can give you.

Feed them a rotation of high-quality sinking pellets, frozen foods like bloodworms and brine shrimp, and blanched vegetables for omnivores. A well-fed fish is less likely to be aggressive and will live a much longer, healthier life.

Creating the Right Environment

Most loaches are nocturnal or crepuscular (active at dawn and dusk) and appreciate plenty of hiding spots. Provide caves, driftwood, and dense plantings to make them feel safe and secure. A comfortable loach is a confident loach that will happily patrol your tank for snails.

Common Problems and Best Practices to Avoid Them

Even with the perfect fish, you might run into a few hiccups. Here are some common problems with fish that eat malaysian trumpet snails and how to solve them using best practices.

Problem: “My new fish isn’t eating any snails!”

Solution: Give them time! A new fish needs to settle in. They might also be getting too much other food. Try reducing feeding for a day or two to encourage them to forage. Also, ensure the snails aren’t too large for the fish to eat.

Problem: “The snails are all gone. What do I feed my puffer?”

Solution: This is a great problem to have! For puffers, you must continue to provide hard-shelled foods. You can buy pest snails from a local fish store or even set up a small snail-breeding jar. For loaches, simply continue feeding them a high-quality, varied diet. They’ll be perfectly happy.

Problem: “My Yoyo Loaches are harassing my other fish.”

Solution: This usually happens for two reasons: their school is too small, or the tank is too cramped. Ensure you have at least 5-6 Yoyo Loaches to allow them to establish a pecking order among themselves. If the tank is too small, their boisterous energy can turn into aggression.

The Eco-Friendly Approach: Sustainable Snail Control

Using fish that eat malaysian trumpet snails is a fantastic, natural solution. This is the heart of creating a sustainable and eco-friendly fish that eat malaysian trumpet snails strategy. You’re using one part of the ecosystem to balance another, rather than resorting to chemical snail-killers.

Those chemicals often contain copper, which is lethal to all invertebrates—including your prized shrimp and nerite snails—and can linger in your substrate for years. A biological solution is always safer and more aligned with the goal of creating a tiny, self-regulating world in your living room.

Frequently Asked Questions About Fish That Eat Malaysian Trumpet Snails

Will these fish eat my decorative snails like Nerites or Mystery Snails?

Unfortunately, yes. Most dedicated snail-eaters, especially loaches and puffers, cannot distinguish between “pest” snails and “pet” snails. If you want to keep beautiful decorative snails, you should not add these predators to your tank. An alternative would be manual removal or using a less aggressive option like a Betta.

Can I just get one Clown Loach for my 20-gallon tank?

Absolutely not. This is a very common but harmful mistake. Clown Loaches need extremely large tanks (125+ gallons) and must be in social groups to thrive. A single, cramped loach will be stressed, unhealthy, and won’t live a full life. Please choose a species appropriate for your tank size, like the Dwarf Chain Loach.

What’s the fastest way to get rid of a massive MTS infestation?

The fastest method is a three-pronged attack. First, manually remove as many as you can by baiting them with a piece of blanched zucchini left overnight. Second, drastically reduce your feeding schedule. Third, introduce a suitable school of snail-eating fish. This combination addresses the root cause and the existing population simultaneously.

Are there any non-fish alternatives for eating MTS?

Yes! The number one non-fish alternative is the Assassin Snail (Clea helena). These carnivorous snails will actively hunt and eat other snails. They are very effective, don’t reproduce as quickly as MTS, and are a great choice for smaller tanks or tanks with shrimp where a fish predator might be too risky.

Your Path to a Snail-Free, Balanced Aquarium

There you have it—your complete roadmap to managing Malaysian Trumpet Snails the natural way. It’s not about eliminating them entirely, but about restoring balance to your beautiful underwater world.

Remember the golden rule: snail explosions are a symptom of overfeeding. By adjusting your feeding habits and introducing the right fish for your specific tank, you’re not just solving a snail problem; you’re becoming a more observant and skilled aquarist.

Choosing the right fish is a rewarding journey that adds new life, behavior, and balance to your aquarium. Go forth, choose wisely, and enjoy your crystal-clear, snail-managed tank!
