Ghost Shrimp - Complete Care Guide

Published: 2026-10-20 · FishyKart Blog

Ghost shrimp (Palaemonetes spp.) are small, nearly transparent freshwater shrimp popular both as aquarium pets and, historically, as cheap live feeder stock for larger fish - and that dual role is the real reason this otherwise easy species has such a mixed reputation for dying quickly. A shrimp bought as an undifferentiated "feeder" from a tank with no real husbandry behind it starts out stressed in a way a shrimp sold specifically for keeping generally doesn't.

Tank Requirements

  • Tank size: 5 gallons (20 litres) minimum for a small group
  • Temperature: 18-26°C
  • pH: 7.0-8.0
  • Filtration: gentle flow - strong intakes can pull in small shrimp
  • Plants/decor: dense planting or driftwood for cover, especially post-molt when the shrimp is soft and vulnerable
  • Medication caution: avoid copper-based treatments in a shared tank - invertebrates tolerate copper very poorly

Why the "Dies Fast" Reputation Exists

Ghost shrimp sold cheaply and in bulk as feeder stock are often held in crowded, minimally-maintained tanks before sale - by the time one reaches a home aquarium, it may already be stressed or weakened. A ghost shrimp bought specifically as a pet, from a seller maintaining proper water quality, doesn't carry that same handicap and tends to do considerably better. The species itself isn't fragile; the supply chain often is.

Molting

Ghost shrimp molt regularly to grow, shedding a complete, translucent exoskeleton that can look startlingly like a second dead shrimp at first glance. Leave the shed shell in the tank - the shrimp will eat it to recover calcium for the next shell. A shrimp is at its most vulnerable in the hours right after molting, before the new shell hardens, so cover is important during this period.

Frequently Asked Questions

Why do ghost shrimp die so quickly after being bought?

A large share of ghost shrimp sold are stocked as cheap "feeder" shrimp rather than long-term pets, often held in poor conditions before sale. A shrimp that's already stressed from that history is far more vulnerable to a sudden move into a new tank than a shrimp sold specifically for keeping.

How often do ghost shrimp molt?

Roughly every few weeks, more often while young and growing. A shrimp that appears to have a second, translucent shrimp-shaped body in the tank has simply shed its exoskeleton, not died - leave the shed shell in place so it can be eaten for calcium.

Is a ghost shrimp truly transparent?

Nearly - the body is largely see-through with only faint colouration, which is exactly why it's easy to mistake a molted shell for a second shrimp, or to lose track of one against a busy substrate.

Do ghost shrimp need a lid on the tank?

Not strictly, but a tight-fitting lid or a water level well below the rim reduces the (low but real) chance of one climbing out via equipment or plant stems.

Can ghost shrimp live with fish?

Yes, with peaceful fish too large to see them as food. Larger or predatory fish will eat ghost shrimp readily given their small size and lack of defences.
