Is it normal to lose fry?Mine are 10 days old.I started out with around 80,now I have maybe 60.They are in a 5 gallon tank by themselves.I feed brine shrimp 3 times a day.I do see them eating the food.I did have a problem with my sponge filter,it wasnt from an established tank,it was new.But I was putting water from an established tank into the 5 gallon every day when I changed the water.I have resolved that problem.But is it normal anyway to lose a certain amount of fry from each spawn?
