Approximately one dozen mysid shrimp to start your culture. Can only ship on Wednesday and Thursday because they take some time to catch. The species we have been fortunate enough to have in our systems is very hardy and has survived for almost a decade now without any special culture at full salinity. Sorry about the shipping schedule restrictions, but Monday and Tuesday are fairly busy days and it takes an indeterminate amount of time to collect them for shipping.
Mysid,or opossum shrimp are an excellent source of nutrition for your picky fish, featuring a good HUFA and protein profile. They will feed on small pieces of detritus in your aquarium.
