Beginner answer
Cherry shrimp works best when tank mates match its 5+ gal / 19+ L minimum, group needs, and temperament. Start with the concrete limits: tank volume, adult size, temperament, group size, water range, and filtration margin.
Top beginner-safe picks
- Same temperature range - Tropical fish usually need 72-82 F; mixing coldwater and tropical fish causes chronic stress.
- Similar aggression level - Peaceful fish belong with peaceful fish; avoid fin-nippers with bettas, guppies, or angelfish.
- Matching pH range - Most community fish tolerate pH 6.5-7.5, but sensitive species still need stable water.
- Appropriate tank size - Use the larger species minimum, not the smaller fish minimum.
- Schooling group size - Neon tetras, rasboras, and Corydoras show stress when kept alone.
Cherry shrimp (Neocaridina davidi) should be judged by adult size and group needs, not by the small size it may have at the store.
Setup rule: Cherry shrimp has a minimum tank size of 5 gallons and a recommended tank size of 10 gallons.
Setup rule: Temperament: peaceful shrimp. Beginner friendliness: medium. Bioload: very low.
Setup rule: Better tank mate candidates: nerite-snail, ember-tetra. Risky or avoid lists should be treated conservatively until the full setup is checked.

Cherry shrimp quick care verdict
Cherry shrimp (Neocaridina davidi) is currently marked medium for beginner friendliness with medium confidence. The minimum tank size is 5 gal / 19 L, but 10 gal / 38 L gives better margin for behavior, filtration, and maintenance.
| Scientific name | Neocaridina davidi |
|---|---|
| Adult size | About 1.2 inches |
| Tank size | 5+ gal / 19+ L minimum; 10+ gal / 38+ L recommended |
| Temperature | 65-78 F |
| pH | 6.5-8 |
| Group size | 6 or more. Best kept as a small colony. |
| Temperament | peaceful shrimp |
| Bioload | very low (0.25 care score) |
Tank setup
Use the recommended tank size as the real target. The setup should match the fish's adult size, activity level, bioload, and group requirement. Plant cover is helpful because it creates security and visual breaks. Hiding spots should be treated as part of the setup, not decoration.
Behavior and group size
Group behavior changes compatibility. Best kept as a small colony.
Aggression risk is marked low, fin-nipping risk is marked none, and predation risk is marked low. These labels drive the compatibility checker, especially when the other fish is long-finned, tiny, slow, or shrimp-like.
Tank mate shortlist
Better candidates
Nerite snail, Ember tetra
Use caution
Betta, Guppy, Platy
Avoid
Goldfish, Angelfish, Pea puffer
Betta compatibility
With bettas, this species is marked possible with caution.The main reasons are: Bettas may eat shrimp Dense plants and hiding spots are important Shrimp do best in stable mature tanks
Beginner warnings
- Bettas may eat adult shrimp or young shrimp.
- Dense plants and hiding spaces are important.

Warnings
These are the failure points that hurt beginner tanks most often. Do not use guide content as a guarantee. Watch actual fish behavior, test water, respect adult size, and keep a backup plan if stress appears.
- Tiger barbs - Confirmed fin-nippers; do not keep them with bettas, angelfish, guppies, or other long-finned fish.
- Goldfish - Coldwater, high-waste fish that do not belong with warm tropical community species.
- Angelfish - Adults become territorial and may eat very small fish such as neon tetras in cramped tanks.
- Pea puffers - Aggressive hunters that bite fins and attack snails; treat them as species-only unless experienced.
- Temperature mismatch - White cloud mountain minnows and goldfish prefer cooler water than bettas and many tropical fish.
Editorial notes
How this page is maintained: This page is updated from local care data, compatibility rules, source notes, and conservative beginner-risk checks.
This page uses conservative local care data, explicit compatibility records, and established aquarium care references rather than store-label shorthand.
Combinations are reviewed before they are promoted as indexed guides, and uncertain pairs stay cautious or marked as needing more research.
The recommendations are intentionally conservative because most readers are planning beginner tanks, where water quality and backup options are limited.
