Some of the trout got eaten bye the bigger trout. The trout have red and orange fins this year.The brook trout are now over 1 inch this year and there called “parr” or “fingerlings”. but the best part about trout in the class room is we get to learn about the trout and it helps us learn or at least me.The brook trout are amazing but sometimes the big ones eat the little ones i know it sounds gross but its a part of fish life.They are healthy this year.The bigger brook trout stay at the top. The middle brook trout stay in the middle. The small brook trout stay at the bottom of the tank.The brook trout have to survive if there small.
