Its Dead. When it floats up and the gills are not moving and breathing for sure it is dead
if theres are other fish in the tank with him then his tail is getting eatin by the other fish and u need to get him out now. or he might just have fin rot.
If there is other fish in the tank he doesn't like them or he could have air in his body which floats him to the top and they can die from that .
its dead.. Sorry, but I think your fish is dead! :(

Some fish prefer swimming at the top of the tank while others the bottom or middle.
Could be anywhere.
