I know of someone else who found a similar thing. There appear to be more than one 'variety' of mysids out there, one being more predatory and a danger to young cephs.Indiana OCHO;86846 said:The babies made it for a week and then began to die off. I thought they needed more food, but that wasn't it. In fact it was the food that was the problem. The mysids were attacking the babies. So be careful with those guys, you have done so well and they look great.
