科: Palaemonidae
幽灵虾是原产于美国东南部的透明虾 Palaemonetes paludosus，俗称玻璃虾。成体 3–5 cm，18–28 °C 非常皮实，胆大的除藻工；透明身体能看清内脏与抱卵，堪称活体解剖课。
Ghost Shrimp is the glass-clear Palaemonetes paludosus from the southeastern United States, sold everywhere as an inexpensive 'glass shrimp' for algae duty — and frequently underestimated. Its body is almost entirely transparent, organs, gut contents and even a clutch of green eggs visible as if through a window, which makes it a living anatomy lesson and a fascinating algae eater at the same time. It grows to 3-5 cm, tolerates 18-28 °C across a wide pH range, and handles conditions that kill fancier shrimp, though it appreciates the same clean, stable water as any invertebrate. In the aquarium it is an active, bold forager that picks food from plants, glass and gravel, and it swims openly even in bright light. Breeding is possible in freshwater: the female carries 20-30 eggs that hatch as tiny larvae needing microscopic food — most clutches vanish into filters or get eaten, but occasional juveniles appear in dense plantings. Peaceful with everything too small to eat it, and best kept in groups of five or more.
适合新手。Peaceful but opportunistic；Groups of 3 or more。
建议水温 18–28 °C，18–28 °C stable range；Stable 18–28 °C; very tolerant。
成体 3–5 cm 左右，因其Bottom — transparent ghost cruising plants的习性，30 L 以上的缸更合适。
Omnivore-scavenger; accepts all foods, including detritus。建议人工饲料搭配冷冻或活饵，保证多样性。
Peaceful but opportunistic；Groups of 3 or more。理想混养对象：Virtually any peaceful community fish — Hardy enough for beginner community tanks, Other shrimp species — No aggression between shrimp, Snails and peaceful bottom fish — Shares the cleanup crew。需避开Copper-based medications — Lethal to all invertebrates, Large predators — Even ghost shrimp are eaten by big fish, Anabantoid bettas with attitude — May harass or nip at molting shrimp。
原生于North America — southeastern United States，栖息于Warm springs, swamps and slow streams with vegetation。Still to gentle current，Moderate oxygen。
该物种会跳缸——缸盖务必盖紧，换水时尤其注意。
人工环境下：Breeds in freshwater but the eggs hatch as free-swimming larvae needing infusoria or powdered foods; survival in a planted tank is occasional rather than guaranteed. Females carry 20-30 green eggs visibly through the transparent abdomen.。Females are larger and deeper-bodied with a visible green egg mass; males slimmer and smaller.。
