Can you give us some more info? Water params, any new fish, how long you'd had this guy, any other symptoms?
BTW, I could be wrong, but I believe a standard 2ft tank is about 15 US gallons, which is very small for the fish you have. I don't know if you're already aware of this, or planning to upgrade or anything, but I figure better to be safe than sorry
I hope everything goes ok, & if you can give us a little more info, I'm sure some smart cookie here will know what went wrong. Goodluck
the tank is running ok no probs with the water.
the tank is ok for the size my dad knows loads about fish and tropical so he told me the size is ok.
he would give me a bigger one if the size was wrong.
the puffer did not have eny symptoms all that i could think of is that he puffed up and died as he was lying on the gravel.
