Hi all, I've noticed that when reading information on schooling fish, that everything says "groups of six or more"... Why six? Why not seven or five?
I understand the reasons for keeping certain fish in groups, but I can't understand why a minimum of six. Have any studies been done on such things? How do we know that a group of six corydoras isn't just as anxious or uncomfortable as a group of four in the same situation? Who's to say that groups of 15 shouldn't be the minimum? Maybe 'six' is a number that someone has pulled off the top of their head that just caught on? I want to know, why six?
I would love to read any studies that have been done in the area, if anyone knows of any can they please link me?
Thanks in advance. Also, please, no arguing, if your opinion differs from someone else's, just agree to disagree or politely post facts to support your opinions - after all, facts are what I'm after.
