You could, another member on her ate his red devils. I have 6 mozambique tilapias, but I don't have any plans on eating them. That and they are only a couple inches long and way to hard to clean, lol.
You have to keep them in clear, running (flowing) spring water (called polishing) the last week without feeding before you eat them.they taste bad if you do not know how to rid it of that freshwater fish smell
If i want to eat fish i just catch them or go to the market.I don't have enough room for a cow. A dog... I'm filipino and we eat dogs... mmm adobo.
