The Puffer Forum

I have an avocado puffer that recently got surrendered to me from work .he was in a larger tank and now is in a 20 gallon long. he is still a juvenile but now will not eat, I have only had him for about three days the tank was cycled for about two weeks, with filter media from another tank and he is glass surfing I also offered a live snail the only thing I can think is that he would be stressed from going from A larger tank to a smaller tank

I'm moving this to the Hospital forum so you can answer all the questions above, in red.
