If my fish is floating on top of the fish bowl what does that mean? my mom wont tell me. did he learn a new trick?

Usually when a fish floats to the top of the water the fish is deceased, maybe from an imbalance in the PH levels of the water or lack of nutrition, etc. Hope this helps! let me know if i can help any further

I hate to break it to you but your fish has decided it wants to swim in the ground instead of water, go burry it in the back yard.
