The Low-Maintenance Red Cherry Shrimp Guide

Yes — Red Cherry Shrimp are widely considered the best shrimp species for beginners. They're hardy, adaptable to a range of water parameters, and will breed readily in a stable tank without any special intervention. Unlike more sensitive species (Caridina shrimp like Crystal Reds), Neocaridina davidi can thrive in tap water conditioned with a dechlorinator. They also have a low bioload, meaning a small group won't destabilize your tank's nitrogen cycle. The key to success is a fully cycled, mature tank with plenty of hiding spots and biofilm — if you provide those basics, cherry shrimp practically take care of themselves.

Start with 10-15 shrimp for a dedicated shrimp tank, or 6-10 for a community tank. A larger starting group gives you genetic diversity, a better male-to-female ratio for breeding, and makes the shrimp feel safer (they're more confident in groups). At minimum, get at least 6 — with fewer than that, you risk ending up with all males or all females and no breeding. If you're adding them to an established community tank with fish, start with 10 and provide dense plant cover so some can avoid predation while the colony establishes. Shrimp are inexpensive enough that starting with a proper group is far better than trying to start with 2-3.

Cherry shrimp are omnivorous scavengers that eat biofilm, algae, decaying plant matter, and leftover fish food. In a mature planted tank, they can survive largely on naturally occurring biofilm. For a healthy diet, supplement with: blanched vegetables (zucchini, spinach, cucumber) once or twice a week, specialized shrimp pellets or wafers 2-3 times per week, and occasional protein like frozen bloodworms or Bacter AE for biofilm development. Key feeding rules: feed sparingly — a single pellet per 5 shrimp is plenty; remove uneaten food after 2 hours to prevent ammonia spikes; and fast one day per week. Overfeeding is a far bigger risk than underfeeding.

If your shrimp aren't breeding, check these common causes first: (1) Water parameters — shrimp breed most readily at 72-78°F, pH 6.5-7.5, GH 6-8. Temperature too low slows metabolism and breeding; too high stresses them. (2) Not enough males — you need at least 2-3 males per female for reliable breeding. Males are smaller, less colorful, and have a straighter body shape. (3) Immature tank — shrimp need a well-established tank with plenty of biofilm; tanks under 2-3 months old may not have enough microflora. (4) Predation — if you have fish, baby shrimp may be getting eaten before you ever see them. Dense moss coverage dramatically improves survival rates. (5) Copper — even trace amounts from fertilizers or medications are lethal to invertebrates.

Yes, but choose tank mates carefully. Safe fish include: small tetras (Neon, Ember, Green Neon), Otocinclus catfish, Corydoras (Pygmy, Panda), Chili Rasboras, and Kuhli Loaches — these species have small mouths and peaceful temperaments. Risky fish to avoid: Betta fish (some ignore shrimp, others hunt them aggressively — it's individual), Angelfish, Gouramis, large tetras, and virtually all cichlids. Even "safe" fish will eat baby shrimplets given the chance. To maximize survival: provide dense moss (Java Moss, Christmas Moss) and floating plants where babies can hide, introduce shrimp first and let them establish before adding fish, and keep the tank well-planted with 70%+ coverage.

When shrimp die individually over days or weeks rather than all at once, the cause is usually chronic rather than acute. Check these in order: (1) Copper poisoning — test your water and check all fertilizers, foods, and medications for copper content. Even low levels that are safe for fish can kill shrimp over time. (2) Failed molts — look for a white "ring of death" around the midsection. This indicates insufficient calcium/magnesium (GH too low) or too-rapid parameter changes. (3) Old age — cherry shrimp live 1-2 years. If you bought adults, they may simply be reaching end of life. (4) Starvation — in very clean new tanks without established biofilm, shrimp slowly weaken. Supplement with Bacter AE or shrimp-specific foods. (5) Planaria or hydra — these tiny predators can kill weakened shrimp. Inspect your glass closely with a flashlight at night.
