To keep the little ones safe, relocate the adults to another tank after they've laid their eggs or released their fry. Water should be changed frequently, and ammonia and nitrite levels should be zero. Churning water can be dangerous to fragile fry. A range of 76 to 80 degrees Fahrenheit is good for most common tropical freshwater fish. Baby fish must eat at least four to six times a day.
