Arowana ate a magnet.

The so-called geomantic omen is actually a kind of magnetic field and orientation, which is to find out the influence of orientation on people through the magnetic needle on the compass and mathematical calculation. It's unusual for your fish to eat magnets. Maybe it was accidentally swallowed by a fish. According to the size of your fish, it should be difficult to eliminate, but it should not affect the health of the fish. It should be noted that it is best to feed concentrate in the future, because if the feed particles are coarse, it will cause damage to the stomach wall of fish. As usual, it should not have much impact on your feng shui. After all, the magnet is weak, but you need to pay attention to the position of the fish tank. You can ask me if you don't understand, I hope it will help ~
