Eventually these fish will need to be graded so that one fish does not get an advantage over the others. the above and below photos show the size differential. It is also worth noting the tiger stripes on these fish which I believe are badly named,Cleary they can change there colour to suit the background there in. I would welcome others opinions on this topic I would prefer something like southern cod or marbled cod please let me know weather they should be renamed or not or offer your name.
