Our trout are hatching! They are emerging from their egg and are becoming emerging fry. Now we predicted our trouts hatching by using FTUs a unit used to measure fish egg birth dates.They also stand for Fahrenheit Measurement Unit.And because fish hatch based on temperature we can predict their birth date.But our teacher Mrs. Wiltrout left the cooler unplugged it for a WHOLE DAY! Which dramatically sped up the birth date and skipped two days! So lately we seen them turning into emerging frys. And in 5-7 weeks they'll need to be fed. Our tank holds about 30 gallons. And is usually at a normal temputure.
