my pike has been in the tank for 2 weeks now. at first he wouldnt eat anything but bloodworms, now he'll eat floating pellets, FD shrimp/krill, and frozen krill. he eats like a pig. he's showing alot of yellow and some red in the tail. at first i thought he was a sveni but now seeing peoples pics of frenata he looks an awful lot like one. ive been able to get some good pics too. what do you experts think?
