I currently have 3 harlequin rasboras with a betta and some shrimps in a 14 gallon tank planted tank (55lt gross measure..a little less taking in consideration the space occupied from the gravel). The front of the tank is 59cm long.
I was wondering if I should simply up the numer of the harlequin rasboras to 8 or if I can introduce some espei rasbora since they are smaller. Would they school togheter?
Any suggestion is welcomed. Thanks in advance.
