no, they always float to the top. b/c, there body has no more food & stuff. its just air. so that's why they float. ;)
not iron
No it wil float to the top of the water.
The fish maybe have a pregnant.
yes
sick fish loose their color they swim less they hide they stay at the corner they stay at the top or bottom of the tank
No they don't. I've had two crabs die in my aquarium and they stay at the bottom.
Yes. Just like we would if we died in waterTheir corpses become bloated with decomposition gases and this causes them to float, much like a balloon would. And because muscle mass is much denser in a fish's back, this tends to turn the fish upside down.If they are on their side, yes. It is unusual for a fish to just float to the top of the water and stay there for awhile. It is their instinct to keep swimming around more towards the bottom of the water, unless food is thrown onto the top of the water.
it looks tried and swims slow and stay on the bottom
Density of the substance will always stay the same. Density of the object will also stay the same if solid, no matter the size, but not if it is carved out. That is why a steel boat can float
depending on the other types of fish or he could be autistic or RETAARRDED
i think that so that they could eat stuff on the bottom or release liquid or droppings
An egg will float in salt water because the salt makes it denser and allows the egg to stay near the surface. But in regular water it will sink straight to the bottom.
