he's of a brilliant yellow, and his belly is white..his eyes are of a deep blue.
Sometimes he moves only one of the lateral fins and keep the other fixed to his body.
yesterday he stopped to move both and was on the bottom coiled up..then the man who sold me the puffer told me to put three or four spoons of salt in the water and the fish started to swim quite normally again.
Then he started to rub himself against everything.
according to some articles I read he seems to have worms or parasites, but I'm not sure.
I know pictures are bad and i cant take better ones

I kept the acquarium empty for two weeks before introducing the puffer,as the shopper told me I put in the water everyday the bioactivator(when the acquarium was empty) and when I change the water I put the Acqua-vit.
I'm from rome.
