I am planning on getting a 90g or 110g tank! I would like to put 1 Oscar, 1 Convict, and 1 Blood Parrot with 3 Silver Dollars. Could I get away with that mix in the 90g, or should I get the 110. I will have black substrate, if it wont effect the Parrots color at all. I have nver kept a Blood Parrot, any ideas on what to expect from this mix? What is the biggest pellet size I can feed the Parrot, because having the Oscar means a Hikari Gold Large pellet eventually, could the Parrot eat that? And any other info that you would think could be helpfull for this fish would be appreciated. Thanks
