so i have a 120G tank with lots of drift wood. tank has 2 big dopey oscars who could realy care less about anything unless its food. and a 9 inch jaguar, ive also got a 2 inch blue acara who is taking for ever to grow and 2 chocolate cichlids at about 4-5 inches. new to the tank i have 1 male(7inch) and 2 female(4inch) hypsophrys nicaraguensis, im very interested in picking up a male and female amphilophus festae(red terror), by studying my own fish i dont see why this would be a problem, im just looking for oppinions maybe im over looking something..thanks
