Well, you could touch him, but that's not reccomended. Most likely your fish it dead, or sleeping. I've never heard of a fish playing dead.
ANSWER:
If your fish looks "dead" but is not, it is probably asleep. If it is floating at the top of your tank, it is either dead or dying.
It will usually stop moving, and sometimes just float at the service.
Most species eat other dead fish. My platys, blue gouramis, and glofish all try to eat dead fish or at least peck at them. Lionfish eat smaller live or dead fish, I know for sure.
When it is floating not swimming.
when they are floating on the water
The only fish species that i know of that lives out of water is the dead kind.
you can tell cuz if a fish is just staying very very still with eyes wide open. but they have to be hovering close to an object.
Well yes that is a hard thing to find out because fish don't have eyelids but if a goldfish is upside down or sideways or just sinks to the bottom its dead but if it just pausesit just means its taking a little snooze!
i dont know maybe
YEAH!!!If you know that 2x2=dead fish. (Whoops)
they eat algae and dead fish
If it is dead yes - seagulls will eat just about anything including their own kind
The white fins wont be moving and they will be at the bottom of the tank
