Been running a few years, its my QT tank, the fish that used to live in there are in a bigger tank now.
He is breathing but will not swim or even look at food. He is just sitting there, I thought he was dead at first. I dipped in the net to see if he would react and move but he moved like and inch and thats it. In the last week I noticed the puffer was not very active, usually light colored hanging out by the heater most of the day.
The other puffer looks great, very active, good color, eats like there is no tomorrow.
How do I diagnose Zizi? He looks like he about to die anytime
