What happens if you bring a deep sea fish to the surface?

What does a fish with swim bladder look like?

Fish suffering from swim bladder disorder exhibit a variety of symptoms that primarily involve buoyancy,1 including sinking to the bottom or floating at the top of the tank, floating upside down or on their sides, or struggling to maintain a normal position.

How can eating affect a fish’s ability to swim down?

Pellets or other food that floats at the water surface encourages gulping air. Too much air in the belly of a fish can end up in its swim bladder. This will violate the balance and cause buoyancy issues. Feed sinking food if possible.
