Of course, you can. Ask if you have experience in fish farming or just keep it for fun. Experienced people believe that you will eat slowly after drinking well and maintaining the water quality, because it may be slow when you are wild, so you should be mentally prepared. I have a snakehead, which has been kept in a fish tank for more than two months, and I only ate a loach yesterday afternoon. If you keep it for fun, it will still be released or eaten, without certain equipment and equipment.
