oh ok its better to move them beause if they get too stressed and lay around the grunter will probably start to try and take chunks from them/it.
ive seen spangled perch doing it to GP like three times as big at a shop how can they not see what they are doing?
yeh . anyways grunter is cute but hogs all food. but hes soooooo coool.anywya he only gets 20cm where as jungle perch get 45cma,tilapia get 40, jar gets 60cm bass get 35cm and scat 30cm. and golden perch get 75cm(although i will sell him at 45cm). silver perch are getting given to lfs as they are too aggressive. they will most probably terrorize tank.i will have to see. for all i know the grunter may live in the 4' for his whole life.
