Strange Serpae Tetras?

Tom · December 8th, 2006

I just got 3 Serpaes and after about 10 minutes of them gettin used to the tank and its surroundings, it started schooling with my Harlequins and they all look really cool. Is this normal since they are all about the same shape and size. Please help me out. Thanks in advance.

Most fish that school will school with fish of the same shape. They know by instinct that they are safer in larger groups.
