Go for easy. Feed clownfish dry food. It is healthier for them. Good pellets or flakes. They eat anything but why do you want to feed them baby brine?
When I was breeding clownfish, exclusive frozen food will not have good eggs and will have low hatch rate nest and deformed babies (more deformed anyway) than if you feed them mostly good dry food like Otohime.
When I was breeding Bangai Cardinal, many years ago, I cannot bring baby to maturities with fortified baby brine. They all have neurological problem and have seizure and died. This have been very well documented by many early breeders.
The short of this is baby brine shrimp have poor nutritional value unless it is fortified, by feeding the baby brine with Omega 3 enhanced food. Even this does not result in much better food.
