they still seem to be doing well, captured 2 in one frame, one clearly?! visible (dead center of this photo) the other hiding in the shadows so there must be a number still in there. Live Mysis seem to be the ticket, about to pull the trigger on a third batch. Nothing else I have tried lives long enough to be eaten, glass shrimp or guppies slowly acclimatized to salt still die within 24 hours and even live adult brine don't like the temperature
