There have been a lot of successful captures. Unfortunately, most of what I've read, the larvae die around day 6, 28 or 60ish. Seems to be problems with different stages. These are all in various larval grow-out containers.
They are more difficult to raise then peppermint shrimp. I know of a few ppl who have successfully had Peppermint shrimp raised to adulthood. L. amboinensis have proven more difficult, some suspect to how they feed. There are varied ideas on feeding, from planktonic algea, rotifers, cyclopeeze, BBS.... no clear winnerrs though yet, still lots of trial and error.
