i have eight harlequin rasboras and the two biggest and most colourful ones do this weird thing that looks as if they are sizing each other up. they go beside each other and kinda swim backwards very slowly. their dorsel fins stay very erect as if they are trying to make themselves look bigger. another thing they do is kinda circle each other. what do you reackon they are doing? its quite amusing
