It’s a common question for many aquarium enthusiasts: “Will neon tetras eat shrimp?” You’ve got these vibrant, peaceful little fish, and you’re thinking of adding some interesting invertebrate companions to your tank. But before you introduce your tiny, translucent friends, it’s wise to understand the dynamics between these two popular aquarium residents. The short answer is: yes, neon tetras can and often will eat shrimp, especially smaller ones.

Understanding the Neon Tetra’s Nature
Neon tetras (Paracheirodon innesi) are known for their dazzling iridescent blue and red stripes and their generally peaceful demeanor. They are schooling fish, preferring to live in groups of six or more, which helps reduce their stress and brings out their best colors. While they are usually described as “peaceful community fish,” it’s crucial to remember that even the most docile fish can have predatory instincts.
Neon tetras are opportunistic omnivores. In their natural habitat, they feast on small invertebrates, insect larvae, and tiny crustaceans. This means if something small enough to fit into their mouth wanders by, it’s fair game. For shrimp keepers, this is the key piece of information: if a shrimp, or part of a shrimp, can fit into a neon tetra’s mouth, it’s at risk of becoming a meal.
Which Shrimp Are Most Vulnerable?
The size of the shrimp is the most significant factor in determining its safety. Here’s a look at common aquarium shrimp and their compatibility with neon tetras:
Cherry Shrimp (Neocaridina davidi)
- Shrimplets: These are almost guaranteed to be eaten. Baby cherry shrimp are tiny, defenseless, and look like tasty snacks to a hungry tetra. If you’re hoping to breed cherry shrimp, a tank with neon tetras is not the ideal environment.
- Adults: Adult cherry shrimp, typically growing up to 1 inch (2.5 cm), are a mixed bag. Larger, well-established adult cherry shrimp might be safe from direct predation, but smaller adults or those that have recently molted (making them soft and vulnerable) could still be targeted.
Amano Shrimp (Caridina multidentata)
- Amano shrimp are generally considered the safest bet for coexisting with neon tetras. They grow larger than cherry shrimp, often reaching up to 2 inches (5 cm). Their larger size makes them much less appealing as a meal for the relatively small neon tetra. While a very small juvenile Amano could theoretically be at risk, adult Amanos are typically too big for a tetra’s mouth.
Ghost Shrimp (Palaemonetes paludosus)
- Ghost shrimp are another common, affordable option. Their compatibility with neon tetras can vary. While they are often larger than cherry shrimp (around 1.5 inches or 3.8 cm), they are also quite transparent, which can sometimes make them less noticeable to predators. However, like other shrimp, their juveniles are highly vulnerable, and even adults could be picked on if they are smaller or the tetras are particularly bold.
Tips for Safer Coexistence
If you’re determined to keep neon tetras and shrimp together, there are several strategies you can employ to minimize risks and increase the chances of a peaceful community:
- Choose Larger Shrimp Species: Prioritize Amano shrimp, as their adult size offers significant protection. If you opt for cherry or ghost shrimp, ensure they are mature adults before introduction.
- Provide Ample Hiding Spots: This is crucial. Dense live plants (like Java moss, Anubias, or cryptocoryne), driftwood, small caves, and rock formations create a complex environment where shrimp can hide and feel secure. These hiding spots offer essential refuge, especially for shrimplets or molting adults.
- Introduce Shrimp First: Allow your shrimp to settle into the tank and establish territories before adding the neon tetras. This gives them a chance to learn the safe spots.
- Keep Tetras Well-Fed: A hungry fish is a predatory fish. Ensure your neon tetras are fed a balanced diet of high-quality flakes, pellets, and occasional live or frozen foods (like bloodworms or brine shrimp) twice a day. This reduces their incentive to hunt your shrimp.
- Monitor Tank Behavior: After introduction, closely observe the interaction between your fish and shrimp. Look for any signs of aggression from the tetras or stress from the shrimp. Be prepared to separate them if necessary.
- Consider Tank Size: A larger tank provides more space for both fish and shrimp to establish their own areas and reduces territorial disputes or constant encounters.
The Inevitable Risk to Shrimplets
Even with the best precautions, if you’re keeping smaller shrimp species like cherry shrimp with neon tetras, you should expect that most, if not all, shrimplets will become food. If successful shrimp breeding is your goal, it’s best to set up a dedicated shrimp-only tank or choose fish species that are known to be completely shrimp-safe.
Frequently Asked Questions
What do neon tetras primarily eat?
Neon tetras are omnivores. In captivity, they thrive on high-quality flake foods, micro-pellets, and occasional live or frozen treats like daphnia, brine shrimp, and small bloodworms. A varied diet keeps them healthy and vibrant.
Are neon tetras aggressive fish?
No, neon tetras are generally considered very peaceful community fish. Their aggression is typically limited to fin-nipping if kept in too small a group (less than six) or if they are extremely stressed. However, their predatory instinct towards very small invertebrates, like baby shrimp, is a natural behavior, not a sign of aggression.
What size shrimp can safely live with neon tetras?
To significantly reduce the risk, aim for shrimp that are at least 1 inch (2.5 cm) or larger as adults. Amano shrimp (1.5-2 inches) are generally the best choice, as their size makes them less likely to be seen as prey. Even with larger shrimp, vigilance is always recommended.
What are the best tank mates for neon tetras?
Ideal tank mates for neon tetras include other peaceful, small-to-medium-sized community fish such as other tetra species (e.g., cardinal tetras, rummy nose tetras), rasboras, small peaceful barbs, dwarf gouramis, corydoras catfish, and Otocinclus catfish. Avoid large or aggressive fish that might see the tetras themselves as prey.
Can cherry shrimp truly live with neon tetras?
While adult cherry shrimp *can* sometimes coexist with neon tetras, it’s not without risk. Shrimplets are almost certainly going to be eaten. If you want a thriving cherry shrimp colony, a separate tank without predatory fish is highly recommended. If you’re okay with losing all the babies and potentially some smaller adults, you can try, but be prepared for losses.
Final Thoughts
Keeping neon tetras and shrimp together is a delicate balance. While it’s not impossible, especially with larger shrimp like Amanos and a well-planted tank, it’s important to go into it with realistic expectations. Neon tetras, despite their peaceful reputation, are opportunistic feeders. If you prioritize the safety and breeding of your shrimp, a dedicated shrimp-only tank or choosing truly shrimp-safe fish is your best bet. However, for those willing to take on the challenge, careful planning and observation can lead to a beautiful and dynamic community aquarium.
