In terms of changes in out ecosystem I wouldn't say that there was a pattern. Our water quality and activity in our fish were very inconsistent. The only time I saw consistency was near the end of the project. During that time the fish were a lot calmer and our nitrogen and ammonia levels remained low. Before this we would have one day when the turtle was super active and be eating a lot, but the next day he would lay motionless and eat almost nothing. As for plants, none of them really survived, in fact they would always kinda die out.
