Would a tank with 4 Severums,4 Blood Parrots,6 Silver Dollars, and 4 Blue Acaras be ok?. How are these fish regarding care and compatibility. And how big(u.s. gallons) of a tank could this amount of fish hold?. I was just wondering if these fish are easy for a newbie to take care of. I think this would be a cool show tank IMO.*thumbsups
