10 Safe Tank Mates for Shrimp: A Comprehensive Guide
Why is Picking the Right Fish Important?
I have made plenty of mistakes in my fish-keeping days. One time, I dropped a group of fancy guppies in with some shrimp, thinking they would be fine because, well, guppies are small, right? Guess what happened next? Those guppies did not waste any time going after the shrimp fry like they were at an all-you-can-eat buffet. Lesson learned.
The truth is, shrimp are small and vulnerable, and not every fish is going to respect that. You need to think about things like how aggressive a fish is, where they like to swim, and if they have a taste for tiny critters. It is not just about picking peaceful fish, but also about choosing ones that will not see your shrimp as an afternoon snack.
Are Neon Tetras Safe for Shrimp?
1. Neon Tetras
General Information
Neon Tetras are small, colorful fish native to the rivers of the Amazon basin in South America. Their bright blue and red stripes make them stand out in any aquarium, and they are known for being peaceful and hardy. In the wild, they inhabit slow-moving waters, often shaded by dense vegetation. These fish are schooling creatures, meaning they thrive in groups, which also helps them feel more secure.
Care
Neon Tetras are fairly easy to care for and can be housed in tanks as small as 10 gallons. They prefer water temperatures between 72°F and 78°F, with a pH range of 6.0 to 7.0, which makes them a great match for shrimp tanks. They are not picky eaters, so you can feed them a diet of high-quality flake food, supplemented with frozen or live treats like brine shrimp or daphnia.
Temperament
These fish are peaceful, and when kept in schools of at least six, they create a vibrant, active display. Neon Tetras tend to stick to the mid-levels of the tank, so they do not compete with shrimp for space. They will rarely, if ever, bother adult shrimp, though you might want to keep an eye out if you have shrimplets (baby shrimp) in the tank.
Insider Tip
In my tanks, Neon Tetras have always coexisted peacefully with shrimp. One trick I have found helpful is adding some floating plants, which not only make the Tetras’ colors pop but also help them feel safe and comfortable. The added shade calms them down, and the shrimp seem to enjoy exploring the plants too.
Can Otocinclus Catfish Coexist with Shrimp?
2. Otocinclus Catfish
General Information
Otocinclus Catfish, or “Otos” as they are affectionately called, are small, algae-eating catfish that come from South America. They thrive in fast-moving streams where they feed on algae that grows on rocks and plant surfaces. Otos are small, maxing out around 2 inches, which makes them ideal for nano tanks. They are well-known for their hardworking nature, constantly grazing on algae, keeping the tank clean.
Care
Otos need a bit of extra care when it comes to water conditions. They do best in tanks that are at least 20 gallons, with temperatures between 68°F and 78°F, and a pH of 6.5 to 7.5. They require clean, oxygen-rich water, so make sure you keep up with regular water changes. Their diet is primarily algae, but if your tank does not produce enough naturally, supplement with algae wafers or blanched vegetables like zucchini.
Temperament
Otocinclus are incredibly peaceful, shy fish that prefer to stick to the surfaces of plants or the sides of the tank, scraping off algae. They pose absolutely no threat to shrimp and are great companions in shrimp tanks. These little guys do best when kept in groups of at least three to six, as they are social creatures and feel more secure in numbers.
Insider Tip
One thing I learned the hard way is that Otos are sensitive to new environments. They need a well-established tank with plenty of biofilm and algae to graze on. If your tank is too new, they might struggle. In those cases, feeding them Hikari Algae Wafers is a lifesaver.
Do Corydoras Catfish Harm Shrimp?
3. Corydoras Catfish
General Information
Corydoras, or Corys, are small, bottom-dwelling catfish that hail from slow-moving rivers and streams throughout South America. There are many species of Corydoras, but they all share similar traits: they are peaceful, social, and playful. Their bodies are covered in a protective layer of bony plates, making them more armored than your average fish. They use their whisker-like barbels to forage for food along the substrate, adding to their charm.
Care
Corydoras need at least a 20-gallon tank with a soft, sandy substrate. They love to root around in the sand, so make sure the substrate is gentle on their sensitive barbels. Keep the water temperature between 72°F and 78°F, and aim for a pH of 6.0 to 7.0. Corydoras are omnivores, meaning they will eat just about anything that sinks to the bottom. Feed them a mix of sinking pellets, live or frozen food like bloodworms, and the occasional veggie wafer.
Temperament
These catfish are peaceful, friendly, and very social. Corydoras are happiest when kept in groups of five or more. You will often see them swimming and foraging together, which is fun to watch. They leave shrimp alone and are perfect for community tanks. They are active, but not aggressive, and their bottom-dwelling habits mean they will not interfere with shrimp activities.
Insider Tip
In my experience, Corydoras are some of the most entertaining fish to watch. They are constantly moving around, foraging for food. One thing to keep in mind: make sure the shrimp have plenty of hiding spots like hide caves or moss balls because Corydoras are curious and will investigate every corner of the tank.
How Do You Keep the Peace in a Shrimp Tank?
Choosing the right fish is only part of the equation. To ensure harmony in your shrimp tank, make sure your shrimp have plenty of hiding spots like moss balls, hide caves, and driftwood. This is especially important during molting, when shrimp are vulnerable. Also, keep an eye on the behavior of your fish, particularly during feeding times. Well-fed fish are less likely to get curious about shrimp. Keep your water clean and stable, and you will have a peaceful, thriving shrimp community tank in no time.
