I was just wondering why you have to wash off bbs before you feed them to your fish.
I'm pretty sure it's to rinse the salt off. I never have any luck hatchig them.
Found it. Guess I'll post the answer so others know. Rinse: The warm incubation temperatures and metabolites from the hatching medium create ideal conditions for a bacteria bloom. Rinsing of the baby brine shrimp in a fine mesh net or sieve using clean fresh or salt water is important before feeding them to your fish.
