Yes, most baby fish (fry) can swim soon after they are born or hatch.
While the exact developmental stage at which a baby fish can swim varies depending on the species, the general answer is yes. The reference highlights that some baby fish, particularly those born live (as opposed to hatching from eggs), are more developed at birth and can swim immediately. These "live-born" fry are more mature than newly hatched fish from eggs and possess the necessary motor skills and physical development to swim effectively from the start. This capability is essential for their survival as it allows them to search for food, avoid predators, and navigate their environment. In egg-laying species, the fry may not swim immediately upon hatching, but they will typically develop the ability to swim within a relatively short period as they absorb their yolk sac and mature.
