About 18 months after going vegetarian one of my friends invited me to her house for dinner and I promptly mentioned that I was a vegetarian but fish would be OK. My friend said that I wasn’t a proper vegetarian because fish was also meat. I had always placed fish in a slightly different category simply because it was a sea rather than a land animal.
However, when I really took the time to consider this, it was clear that the medium in which an animal lived had no bearing upon its sentience. Indeed my own 2 fish would swim up to the edge of their tank ‘asking’ me for food and they would show fear when I had to remove them from their water to renew it. In fact, they would generally hide for a day in their tank after their water had been refreshed. It took them a while to become accustomed to this ‘new’ environment. I could see from this behaviour that they, too, had feelings and that it could not be right to eat fish.
Now I realized that, indeed, I was not a fully fledged vegetarian but I was what is termed a ‘pescatarian’. After I had come to the realization that fish, too, were sentient beings that deserved to live out their lives without the likes of me killing and eating them, I was now a true vegetarian and I thought that was it — I had arrived!
