i jus picked up a 15" silver from my buddy, he had put it in with a 26" silver that was hella dominant of its tank. the lil guy got beat to ****. so many scales are missing it made me sad. so i took it from him for free hoping to save it. its so skinny because it prolly hasn't eatin in like a week and its been so damn stressed. i put it in my tank and it seemd to get weaker. started swimming sideways, upside down. now its tail is like dropped n its jus floating with its tail slightly curled at the bottom of the tank floating in an upright position. its still breathing. it looks around because i can see its eyes moving. but its jus sittin there. is there anything i can do for it? im scared for it and really dont want it to die.
