Peer Edits II I focused specifically on the Behavior section of this article Hyperlinks I added Shoaling olfactory altruistic alertness northern pike From the section Alarm substance The production and release of this alarm substance are altruistic because the sender of the signal who does not directly benefit from the signal released upon its injury has to pay the cost for the production and release of the chemical I found this sentence to be extremely confusing so I tried to fix it up The author should go back and try to further clarify it though I also made quite a few wording edits to this section I added in spaces between the paragraphs which were absent before This should make everything in the article look a little cleaner The section on Predator inspection was very good and thorough I just made some sentence structure and wording changes The author may want to consider clearing up the second paragraph about the minnows interactions with the Northern Pike Overall this was very well written and pretty thorough I made minor wording changes but did not do anything major My suggestions for the author are below Suggestions for the author In the Shoaling section clarify what you mean by increased risk of infection Are there specific diseases or parasites that affect this minnow Clarify where you talk about how na ve common minnows The shoaling section was very broad and could probably be expanded upon to be more specific to minnows Right now it seems like it is just talking about fish in general In the section Shoaling adjustment in response to predation risk talk about why those individuals in the central group are in the best position Expand on the Foraging section perhaps talk about their diet and how that relates to shoaling behavior being beneficial
