Best Schoolers

Harlequin rasbora. The bigger the group the better the schooling behaviour

Since theres nothing that really gets big enough to eat them what about a massive group of Ember tetra

my espei rasboras travel around in a really nice group but my cardinals don't as much and I think they are boring, though night to look at.
