Best Tank Mates for Neocaridina Shrimp — Peaceful Fish, Snails & Companions That Won’t Eat Your Shrimp

Neocaridina shrimp (commonly sold as Cherry Shrimp, Blue Dream, Yellow Goldenback, and many more colors) are some of the most popular invertebrates in the freshwater hobby — colorful, peaceful, easy to breed, and excellent algae grazers. But picking tank mates is where most new shrimp keepers go wrong. The wrong fish will eat your shrimplets faster than your colony can replace them; the right fish will let your colony double every few months and add motion and color to a planted tank. This guide walks through the best (and worst) tank mates for Neocaridina, plus the setup choices that protect baby shrimp.

What Makes a Tank Mate "Shrimp-Safe"?

Four factors decide whether a fish is safe with cherry shrimp:

• Mouth size: if a fish's mouth is big enough to fit a shrimplet, it will probably try. Stick to nano species with tiny mouths.
• Temperament: calm, slow-feeding fish are safer than fast, opportunistic hunters.
• Water parameter overlap: Neocaridina thrive at pH 6.8–7.8, GH 6–8, KH 2–5, and 65–78°F. Pick fish that prefer the same window.
• Planted cover: the more java moss and dense plants you provide, the more shrimplets survive. Cover is the single biggest predictor of colony growth alongside fish.

If you haven't dialed in shrimp water chemistry yet, start with our shrimp water parameters guide and the shrimp tank setup guide before adding any fish.

Tier 1: Truly Shrimp-Safe Fish

These species are widely considered the safest choices for active breeding colonies. Adults won't actively hunt shrimp, and shrimplet predation is rare in a well-planted tank.

Otocinclus Catfish

The classic shrimp-safe algae grazer. Otocinclus spend their day grazing biofilm and soft algae from leaves and glass — they pose zero threat to shrimplets and actively complement shrimp by cleaning surfaces too small for shrimp claws. Keep in groups of 6+.

Chili Rasbora

Tiny, red-orange schooling fish from Borneo. Chili rasboras max out around 0.7 inches with mouths smaller than a sesame seed — they physically cannot eat even newborn shrimplets. They prefer soft, acidic, planted tanks, which is exactly where Neocaridina thrive. See our chili rasbora care guide for details.

Dwarf Emerald Rasbora

A vivid green-and-black nano gem from Myanmar. The dwarf emerald rasbora shares the same micro-mouth profile as the chili and adds striking lateral barring to your aquascape.

Celestial Pearl Danio (CPD)

One of the most beautiful nano fish in the hobby — deep navy bodies, pearl spots, and ruby-red fins. Celestial Pearl Danios are slightly bolder than chilis but still safe with adult Neocaridina. Heavy moss cover protects newly hatched shrimplets.

Clown Killifish

Surface-dwelling, tiger-striped, and rarely descending below the top inch of water. Clown killifish almost ignore shrimp because they're focused on the surface. A favorite for nano planted tanks with floating plants.

Sparkling Gourami

An exception to the "no gouramis with shrimp" rule. Sparkling gouramis max out at 1.5 inches and have small mouths. They might pick off the occasional newborn shrimplet, but established colonies handle the predation easily.

Tier 2: Generally Safe with Caveats

These species are safe with adult shrimp but will hunt shrimplets opportunistically. Add only to a colony that's already well established (50+ adults) and has dense moss/plant cover.

Ember Tetra

Glowing orange schooling fish that stay around 0.8 inches. Ember tetras ignore adults but will eat unguarded shrimplets in open water.

Green Neon Tetra

A smaller, hardier cousin of the cardinal tetra. Green neon tetras are calm schoolers — see our neon tetra care guide for general tetra care — but their adult mouth can fit a tiny shrimplet, so coverage is essential.

Pygmy & Tailspot Corydoras

Nano cory catfish that occupy the bottom. Pygmy corydoras and tailspot pygmy cory share the substrate with shrimp peacefully. They occasionally sift up molts and unwary shrimplets, but never adults.

Kuhli Loach

Long, eel-like bottom dwellers that mostly ignore shrimp. Kuhli loaches are night-active and will occasionally hunt molts; full care details in our kuhli loach care guide. Best paired with established colonies that produce more shrimplets than the loaches can find.

Endlers

The smaller cousin of the guppy. Endlers are colorful and active but will hunt shrimplets, so they're a "fish first or established colony" pick. Their breeding habits also mean you'll see a lot of fish fry in the tank.

Best Snail Companions for Shrimp

Snails are the perfect Neocaridina companions — zero predation risk and they tackle algae and biofilm that shrimp can't reach.

Nerite Snails

Zebra nerite snails are the gold standard algae cleaner. They can't breed in freshwater, so you'll never have a snail explosion. Their patterned shells are beautiful, too.

Mystery Snails

Larger, slower, and gentler. Blue mystery snails add a peaceful presence and graze the substrate without ever touching shrimp. Browse the full snails collection for color options.

Ramshorn and bladder snails are also harmless to shrimp — they'll multiply on their own with extra food in the tank.

Other Shrimp Species That Mix Well

Neocaridina davidi readily share space with other Neocaridina color morphs (they'll interbreed back to wild brown, so isolate by color if you care about genetics) and with these non-interbreeding species:

• Amano shrimp — larger, voracious algae eaters. They occasionally bully smaller shrimp at feeding time but generally coexist.
• Blue Dream shrimp — same species as cherry shrimp; will interbreed (offspring revert to wild brown).
• Red Cherry shrimp — the classic.
• Snowball shrimp — a different species (Neocaridina cf. zhangjiajiensis); won't interbreed with cherry.

For the full lineup, see the shrimp collection and our best shrimp for beginners guide.

Fish to AVOID with Neocaridina Shrimp

These species will hunt shrimp aggressively or eat them outright. Don't add them to a shrimp tank you care about:

• Bettas — hit or miss; many will pick off shrimp one by one until none are left.
• Angelfish — they treat shrimp as a meal.
• Most gouramis (dwarf, honey, pearl, blue) — will hunt adults.
• Barbs of any kind — fast, persistent hunters.
• Cichlids (including kribensis, apistos, rams) — even small ones eat shrimp.
• Goldfish — size and water parameters both incompatible.
• Most loaches (yoyo, clown, zebra) — active hunters of inverts.
• Pufferfish of any species — invert specialists.
• Larger tetras (serpae, black skirt, congo) — mouth size puts adult shrimp on the menu.

Tank Setup That Protects Shrimplets

The right setup turns a marginal fish/shrimp combo into a thriving multi-species tank:

• Use a sponge filter — powered HOBs and canisters suck up shrimplets unless heavily pre-filtered. Sponge filters are safe and double as biofilm grazing surfaces.
• Dense moss cover. Aim for at least 30% of the tank covered in java moss or christmas moss. Shrimplets disappear into moss the moment they hatch.
• Add hides. Cholla wood tunnels and catappa leaves create biofilm and refuge.
• Active substrate (optional). Fluval Stratum buffers pH downward, which helps Caridina; Neocaridina do equally well on inert substrate.
• Stable cycle. Seed the tank with Seachem Stability before adding shrimp or fish.

Water Parameter Overlap Cheat Sheet

Pick tank mates whose ideal parameters overlap with Neocaridina:

• Neocaridina: pH 6.8–7.8, GH 6–8, KH 2–5, 65–78°F
• Chili rasbora, CPD, sparkling gourami: pH 6.0–7.5, soft water, 72–78°F — perfect overlap
• Otocinclus: pH 6.0–7.5, 70–78°F — good overlap
• Pygmy cory, kuhli loach: pH 6.0–7.5, 72–80°F — good overlap (keep towards lower end)

Monitor GH and KH weekly with an API GH & KH test kit — shrimp molting issues almost always trace back to hardness or copper.

Feeding Strategy in a Shared Tank

Fish almost always out-compete shrimp at feeding time. To make sure your colony stays well-fed:

• Feed fish first at one end of the tank; once they're occupied, drop sinking Sera Shrimp Granules at the opposite end.
• Use sinking pellets or wafers from the shrimp food collection rather than flake.
• Feed shrimp every other day; fish daily. Shrimp graze biofilm constantly and don't need much extra.
• Blanched vegetables (zucchini, spinach) are a great supplement that fish ignore.

Frequently Asked Questions

Can a betta live with cherry shrimp?

Sometimes — but every betta is different. Plan for losses and keep dense moss/cholla cover. A 10+ gallon tank with established colonies gives the best odds, but there's no guarantee.

Do guppies eat shrimp?

Adult guppies will eat shrimplets enthusiastically. Adult shrimp are usually safe. If you want shrimp to breed alongside guppies, accept that the colony will grow slowly.

Will tetras hunt my shrimplets?

Most tetras larger than ember/green neon will. Even nano tetras pick off newborn shrimplets. Heavy moss cover and a 50+ adult shrimp colony are the keys to coexistence.

How many shrimp should I have before adding fish?

Wait until your colony reaches at least 30–50 adults and you regularly see berried (egg-carrying) females. A larger population absorbs predation without crashing.

What's the best stocking for a planted 10-gallon shrimp tank?

A 10-gallon can comfortably hold 20+ Neocaridina, a small school of 6–8 chili rasboras or 6 CPDs, plus 2–3 nerite snails. Heavy plants, sponge filter, and weekly water changes.

Can I add fish to an active breeding colony?

Yes, but expect shrimplet survival to drop. Choose Tier 1 fish, keep cover dense, and avoid drastic parameter swings during the transition.

Are amano shrimp compatible with cherry shrimp?

Mostly yes. Amanos are larger and faster at feeding, but they don't predate cherries. House them together with plenty of food to prevent food competition.

Final Thoughts

The best Neocaridina tank mates are small, peaceful, and parameter-compatible — otocinclus, chili rasboras, dwarf emerald rasboras, CPDs, sparkling gouramis, and clown killifish are the safest bets. Add dense moss, a sponge filter, and an established colony, and you can build a stunning planted nano biotope where shrimp breed continuously alongside schooling fish.
