Yes, Marines do.
Freshwater ones take it in through osmosis (through the skin).
Too much salt in the water to use osmosis with marines.

Nope, they don't.
Liquid vitamin supplements are totally useless for freshwater fish because they don’t drink water. Vitamins are best supplemented by first feeding them to brine shrimp which will ingest them and therefore become live “carriers”. Fish can then eat vitamin “enriched” shrimp. The same method can also be applied to medication, using the shrimp as carriers instead of medicating the whole system.

I don't know about salt water, but freshwater fish soak water through their skin, and sometimes, (in the case of dropsy) their kidneys can malfuntion, and they cant get rid of water as fast as they are soaking it up, so their scales pop up and make them look like pinecones!

Aside from what's already been said, I read on a Snapple cap a few times that "fish can drown" too. Crazy.

Saltwater fish do, fresh water fish do not.
