I wanna start a species tank of Vieja (either syn or bifa) do you think this could work in a 300G and how many would I need for the aggression to be spread out well w/o one getting beaten down on all the time. I've kept bifas before and w/o adequate tank space (<150G) and with only one or two other viejas lets just say the others didn't last long with their conspecific rage. Suggestions and comments welcome
