Hi Everyone, My juvenile Steve is floating on the surface of the water listing to the side a bit. He is fed only live black worms. I put him/her in a tank with a larger axie yesterday (yes I may have made a mistake) I saw Steve floating this afternoon and removed him immediately put back into a smaller container. no obvious injuries or damage. the tank is a bare bottom tank with a few floating plants. Steve is my first axie of my own the rest belong to the kids so I am quite worried. Any ideas?
