I have a spiny box puffer that seems to be sick. I noticed he is very inactive, not eating, laboring and sitting at the bottom of the tank. I have him in a tank by himself because I'm worried that if he dies he'll posion the rest of the tank. This happened once before and after a couple of days he was fine again. Last night I did a water change athough all the parameters look ok. Does anyone have any advise?
