common snook requires salt (although i have heard of ones that r full fresh) n grows a lil too big . but ive kept a swordspine snook before which was fully fresh and doesnt get too big. so ya once again, thanks for ur suggestion. perhaps i shouldve posted a list of the ones that i already have kept xD anyway, ur suggestion r definitely in the right direction : )
yes lotsa fish have fins and tails

haha ya i get what you mean though, some looks so vibrant that could be mistaken as sw fish. but just not the general type of fish im looking for.
im looking for "game fish" type , that you would expect in an estuary , but its actually freshwater .
