i have had him for about a week and he has been doing fine. today i get up and he is near the top of the tank wedged between the heater and glass. i moved the heater to see if he was ok and he is swimmin very sporadicly and it looks like his top fin is jsut starting to peel away! the ph and ammonia are great. as the tank is only 2 weeks old. any advice would be great i dont wanna losse this little guy

pics would be good if u can sounds like hes burnt him self or shreading slim
