Lysmata amboinensis is native to coral reefs across the tropics including the Red Sea and the Indo Pacific Ocean. They live on tropical coral reefs between depths of and are typically found in caves or reef ledges. At this point the larvae will settle and metamorphose into a more mature form, though not yet the adult state. This is achieved after several moults which occur every 3–8 weeks. Each shrimp starts out as a male, but after a few moults will become a hermaphrodite allowing them to function as both male and female in interactions with another shrimp; these shrimp have no pure female form. In one spawning, adult shrimp will lay between 200–500 eggs which are initially attached to the pleopods and are greenish in colour; the eggs swell and lighten in colour before hatching and a few will turn silver on the day of hatching. The eggs hatch around dusk releasing long larvae into the free floating pelagic zone. In captivity L. amboinesis have been seen to be socially monogamous showing such aggression that if they are kept in groups of more than 2 individuals one pair will kill the rest. While they are not generally seen in large groups in the wild it is unknown if they are socially monogamous in their natural environment.

Lysmata amboinesis, like other cleaner shrimp, has a symbiotic relationship with 'client' fish in which both organisms benefit; the shrimp gain a meal from eating parasites living on large fish and the clients benefit from the removal of parasites. Removal of parasites under captive conditions happens mainly at night though it is unknown whether this is due to shrimp or host fish behaviour. L. amboinesis is also commonly found living in caves with their client fish, such as moray eels, providing the shrimp with protection from predators. Because of the benefits of cleaner shrimp to the fish they clean, Lysmata amboinensis and other species have been suggested as potentially useful to aquaculture.

Lysmata amboinesis was described and named by Johannes Govertus de Man, published in 1888. In the same year it was also described as Hippolysmata vittata var. amboinensis listing the shrimp as a variant within the species Lysmata vittata. These are now considered synonyms with L. amboinesis a distinct species from L. vittata.

Many species of Lysmata, including L. amboinesis, are commonly kept in salt water aquaria; they are safe and beneficial since they will clean both the tank and fish but not harm corals. For these reasons they are often kept in both home and public aquaria for educational purposes, sometimes in 'touch pools' which allow visitors to put their hand in the water so the shrimp will clean their hand. Despite significant efforts L. amboinesis remains difficult to culture in captivity, though adults will regularly spawn eggs. The cycle from spawning to adult form takes approximately 6 months during which time the vast majority of larvae die.
