The name is that because he's actually the very first inhabitant for this tank. And he's also the only one in the tank. This tank was given to my parents from their friend a long time ago. Never used it till this year, when I got my betta. I don't really plan on getting other inhabitants. (Probably just me worrying about Fuoco catching some disease from them, or him being stressed.) But since this is my first time correctly caring for a betta, for now I'm just keeping him in the tank. Maybe later when I become more experienced, I'll keep snail(s) or shrimp in here too.
No matter how small or big, they are living beings. Take care of your pets
