How many Trophs of one variant does it take to be considered a "colony" ? I ask this question because of all the For Sale threads and post that I read on the Box and other forums . I noticed that some people will have maybe 8 to 10 fish and call that a colony . I don't call this a "colony"..... I call this a "group"or exactly what it is...."8 to 10 fish". I've always considered a "colony" to be roughly 25 fish or more . Maybe I'm wrong so.......I'm just curious as to what other Troph keepers think .
