I have a 16 inch RTG, 14 inch XB and 9 inch SR. I plan to put them all in one comm tank. My tank is 350 gallons (8 x 2.5 x 2.5). Besides the torn fins, dropped scales due to some fighting, does it cause sudden death to one of my fishes ? I am thinking if ever I try this, is it possible to see a dead fish by the next morning ? or will it allow me say about 1 to 2 weeks of observation to see how the fishes will manage being together before deciding to go ahead with the project or quit. In short, I want to know if in 1 or 2 or 3 days is it posible that my fish dies if put in a new community due to aggression ? tks fellow mfk
