even vs odd numbered schools?

actually, there has been a study to prove that humans like odd numbers... but who will notice with 100 fish... if you have less than 20, then it's kinda up to personal preference with tho odd-even
 
Once you have at least 6-8 it no longer matters whether odd or even, nor will sexing matter a great deal. Keep in mind that having more females than males in most types is preferable. Some fish, like giant danios, more males than females are needed but only if you wish to breed.
 
I find it funny that some people seem to think that even numbers are unnatural for some reason.
 
What does this mean ?
There is more chance of seeing a group in odd number being natural than an even number.:grinyes: :laugh:

I don't care about the number honestly. It's all about personal taste.
