My poor Oto died. I found him hanging upside down on my heater after school on Friday. Idk what happened, electrocuted maybe?? Still, he liked the algae wafers, but my Silver Wag decided to play the game, let's keep the algae wafer away from the Oto. She would pick it up, swim around the tank with it, settle down and eat it a little, and then do it again. I don't know what in the world is wrong with her.
