We have had the trout for about 2 months now when we first got the trout there was 35 and no our trout count is still 35!! yay!!!It’s exciting learning all new things about the trout we learned that the trouts parr marks help us tell them apart,we also learned that the bigger ones are more aggressive then the ones in the middle and at the bottom,another thing we learned is that some trout don’t stay with their behavior when their let back into the stream like the bigger trout that it at the top in a tank normal don’t stay at the top in the stream so that way they don’t get eaten by birds hawks anything that will swoop down and eat them instead they will go to the bottom of the stream and hide until dark then they go up to the top of the stream at night and they eat the bugs.
