In single spawning, shrimp will lay around 300 eggs, which are carried under abdomen.

When eggs hatch, they hatch as larval nauplii then going into 2nd larval stage known as zoeae. After free-swimming zoea stage, they’re free-swimming until they settle at around 5-7 weeks. Maturity reached around this time.

They can produce eggs every 10-12 days throughout their lifetime.

Also called Candy Cane Shrimp, Caribbean Cleaner Shrimp, Veined Shrimp, & Western Atlantic Peppermint Shrimp.

Like other members of genus Lysmata, these shrimp hatch as males but after a few molts they’re hermaphroditic functioning as both sexes-there’s no pure female form in any member of this genus. All adults are hermaphroditic.

Many reef aquarists like these shrimp because they eat reef pests as well as clean the tank.
