Hello all, Just wondering if someone can help me out with my Murray cod, I went away for a few days and when i came back my Murray cod was on hes last leg lying upside down in the tank (ph dropped real low) Its been 4 days now in a new healthy tank and hes still alive but still upside down and hardly moving, he just doesnt want to let go, is there any thing i can give him to bounce back or should i put him out of hes misery
