Nice, but honestly speaking, it is not recommended to keep goldfish in a bowl, instead you can keep other fishes like-, guppy, molly, betta fish etc. Every fish has its own requirements just like dogs and cats have, so please it is requested to do some research about any fish before keeping them.
Limited space: Bowls are often too small for goldfish, which can stunt their growth and cause internal organ problems. Low oxygen: Bowls have a low surface to air ratio, and the lack of water movement means oxygen is used up faster than it can be replenished. Poor water quality: Bowls lack filtration, and fish waste and rotting food release toxic chemicals. Temperature fluctuation: Bowls can get too hot or cold, and can be easily knocked over. pH swings: Bowls can experience sudden changes in water pH, especially when the fish is removed for water changes.
