I want a schooling fish that is at least 4 inches in my 80 gallon freshwater tank so they will not be eaten by a senegal bichir. these two seemed like suitable choices but Im torn between the two. so which is better in everyones opinion? any other tightly schooling fish having a maximum length of at least 4" will be considered if you have any suggestions... but I really like scissortail rasbora and giant danios...
