    What would be the best type of material to pour into a cast to replicate the look and feel of a fish? Soft plastic type material?

    please explain......you would "cast" in a mold....the negitive......the "part" or "cast would be the positive end result......what is your mold made of, and what do you want to cast?

    Early on in molding and casting I poured MOLDING latex (Chicago Latex) into a plaster mold and came out with a hollow, SOFT, very flexible fish. I would suppose to do a GOOD job, you would have to put much more molding latex into the mold to get a soft cast that would retain its shape.

    Silicone is another option. PlatSil Gel-10, is a great rtv silicone. A lot of special effects guys use it as it's very flesh like. It would be tougher and not shrink like latex and take a lot less time to set up. If you're doing latex, then it will have to be backed with a foam of some sort. Latex isn't really designed to be cast solid, it would never set up in the middle as it has to evaporate to cure.
