Although I haven't seen any here at Kwajalein for some years now, Gymnodoris striata used to show up periodically at Enewetak Atoll, Marshall Islands. They tended to be on sand and Halimeda algae along lagoon interisland reefs at depths of about 5 to 20 meters. They were not always present, but if I found any at all I'd generally find a bunch, often 10 or more in the same area. I'm not sure where they were coming from or why they would appear all of a sudden. It probably wasn't food, since they liked to eat Plakobranchus ocellatus, which is typically present all the time.
The lower photo shows an animal laying its typical cylindrical egg ribbon.
