Well, if I was going to eat it, I wouldn't go to the expense of setting up an whole aquarium to keep it alive. And if it died despite my efforts to keep it alive, I wouldn't feel safe eating it. So I can't really envisage a situation in which this would be at all likely to happen.
i bet an oscar would taste nice
seems like a very expensive meal, I mean maybe I just pay to much for my fish but for the price of like 5 neons you could go to a sushi bar and have like 6 tuna cuts which would be about 30 times the amount of fish.
