My two angels had a brood of fry on Thanksgiving day, so I hatched some brine shrimp to feed them. The fry are free swimming now, and the brine shrimp are 24 hours old. What do I feed the brine shrimp? My LFS doesn't carry any type of liquid fry food or anything like that, so I boiled an egg, mashed up the yolk with some water, and dropped a drip of it into the brine shrimp cup. Is this sufficient, or are they going to need something else?
