Scientific Name: Palaemonetes paludosus
Common Name: Ghost Shrimp, Glass Shrimp, American Grass Shrimp
Size: 4.5-5cm, males smaller than females
Temperature: 68-80°F / 20-27°C, but can tolerate as low as 50°F / 10°C. Ideal temp. ~23°C
Water Parameters: Can tolerate pH as low as 7, but ideally should be in alkaline water (pH 7.5+) long-term
Food: Almost any algae, fish foods, detritus, snails, worms, vegetables and some fruits. Occassional rabbit pellets and rice acceptable. Will eat almost anything edible
Aggression: See notes
Origin: North America and Mexico
Breeding: Abbreviated larval planktonic stage - larvae are planktonic for a few days and then develop into fully-formed benthic shrimplets. For Palaemonetes paludosus breeding is in freshwater. Berried female should be transferred to separate breeding tank and then moved back once eggs have hatched to prevent predation of larvae by other ghost shrimp. See notes.
Notes: Ghost shrimp are ordinarily considered to be peaceful and any aggression seems to be deemed a case of misidentification (with Macrobrachium sp. usually held accountable). However, there is some evidence this may not always be the case and several breeders have suggested there may be several subspecies of Palaemonetes paludosus with different temperaments. There is certainly evidence of P. paludosus engaging in aggressive behaviour towards each other, occassionally resulting in death, supporting the theory that not all members of this species are peaceful. Ghost shrimp can and do eat their larvae, so if breeding is desired the berried female should be moved prior to the eggs hatching
