clown fry on just baby brine?

Using strictly BBS will usually make the fish susceptible to sudden fright syndrome because of the unbalanced fats. The syndrome will cause the fish to suddenly freak out and die with something as simple as the lights coming or someone walking by the tank. It's definitely possible that is what happened to the majority of them. You should be able to get them on really finely ground pellets or flake foods now.
