Hi Junwei! Thanks for sharing your experiences with M. lohena! We really have to come up with a more appropriate "common" name for these shrimp as "Opae Ula" is exclusively used for H. rubra and saying "Alpha Opae Ula" just confuses the matter. Maybe we can all brainstorm.
In any case..Ken..thanks so much for the info that M. lohena has been found in French Polynesia...I actually found the paper and am reading it right now.
Junwei..these shrimp berry very easily. They don't need to be kept with opa ula...they feed greedily on pretty much anything. Pieces of algae, pellets, flakes. I've never seen them go after my Supershrimp (when I had the M. lohena). The eggs are "intermediate" size which suggests that the larvae shouldn't be floating around for two long. I'm guessing only 2-4 weeks. Technically, either the green water or "fry food" approach should work...but saltwater rotifers may be another option. The problem isn't just food size and quality, but having an established, balanced tank. And then keeping it balanced even with all the feeding. Keep us up to date with your progress. I may try soon also...these are very interesting shrimp but unfortunately not as "care free" when it comes to breeding as the Supershrimp.
