Im brainstorming different options for my schooling fish...doing a bit of reading across various sites im starting to see the only real "schooling fish" is a long spine cardinal
im not really a fan of these as they purely look like something from a fresh water tank and the overall look im going for would see these to look a little out of place.
as i said before these seem to be the only fish considered to successfully school together whilst other fish seem to "shoal" together, and after some time these shoaling species seem to assess that threat is no longer evident and start to pick off each other from smallest to largest or go from being female to male and therefore causing a fight between the 2 or more males in the group.
anyone have any thoughts on the above?
keeping in mind i plan on having 4 borbonius anthias in the tank.
