The fry may survive in the current tank but they can easily starve to death, get sucked into filter, or get eaten by other fish. If u want to save the fry, move as many as u can to a quarantine tank and keep them there until they r old enough to eat with bigger fish and not get eaten themselves.
Feed the babies baby brine shrimp. I recommend raising ur own but u can also buy the frozen cubes. U need to defrost the cubes before feeding.
U can also use fish food ground to dust. U may be able to find that at the bottom of a fish food container or just crush the food with ur own fingers.
It wasnít until 1853 in London when aeration and filtration of water was understood, that people
were able to keep fish as indoor pets.
