so i had, yes had, a baby shark and he was doing great for a month and half. he was eatting and swimming. the temp was 76, sal 1.25 and no metals. all levels were good for the tank, i checked. i was feeding him silversides and krill. he really liked the krill. then he started doing weird spins from time to time. just like when he was eatting. then one night i looked over and he was on the bottom with his belly up. he wasnt dead. i reached in to get him to move around and he would swim alittle and sit normal and then flip back on his back. i tried the peas but i think that i was to late, because he died during the night. does anyone know what i did wrong?
