If you say you want to raise feng shui fish, I really don't have any good examples. It's just what you said, that is, three black ones, two blue ones, two red ones and one white one. I can still match them, but it's hard to say whether they are feng shui fish or not. I know the following kinds of feng shui fish: koi fish is the only cold-blooded fish, koi fish is a kind of feng shui fish, but there are many tropical fish. I know lucky fish, lucky cats (red-tailed cats, paparazzi whales) and warships (also known as ancient warships, Great Bandung, big warships, red-tailed warships, red-eyed warships, etc. ).
If you really want to keep fish of the above colors, I suggest you keep three black Mary, two blue dragons, two red swords and one white Mary. These kinds of fish are tropical fish and are common ornamental fish in the fish market. They are very easy to maintain, the water quality is well regulated, and there is no problem on the whole. If you insist on raising feng shui fish, it is really difficult to find the conditions that meet your requirements.
Well, I wish you success in raising fish!
