I have never seen a fish like this. Anyone have any idea what it is? My assumption is some sort of catfish.

Looks like a walking catfish! I'm from central Fla and came across them time to time

 

Non-native species. 

Is that saltwater or freshwater?

It's not a walking catfish.

Hmmmm...

Was the fish from salt water?  I think it is a Spotted Hake. 

Did you even look at link? I can assure you it's a walking catfish.

The OP even assumes it is some sort of catfish. It would have helped if he photographed it at an angle where you see the barbels.

I'm no expert on FL fishes but I can see why BASS302 would guess it as a spotted hake.  My first thought when I saw the picture was that, assuming it was saltwater, it looked an awful lot like a cusk that we catch in the ocean bottom fishing off shore in New England.  A quick search told me cusk don't inhabit the FL waters so that was out.  I can see it as a hake due to the appearance of the top fin being broken into 2 pieces and the apparent lack of barbels on the top of the nose.  This pic is from Delaware's  DFW page and it looks a lot like the OPs picture

I agree it looks like a hake.

Walking catfish do not have scales.

And there is no barbels or spine on the pectoral fin.

We need a better picture. But I completely agree it looks like a hake?

 

Being From south I've never seen one, but plenty of walking cats. I could be wrong!! Wouldn't be the first

I stand corrected, there is a southern hake, or Gulf hake. I can eat my humble pie ?

@NittyGrittyBoy

The OP never told us where it was caught, but I agree, that's probably it.  I thought it was some sort of hake - didn't know there was a southern hake.  Thanks.  And thanks for the link to walking catfish - I did go to it and learned a lot about walking catfish.  There sure are a lot of strange fish in Florida.

We had armored catfish in my local Lake growing up. Kinda crazy fish. Florida sure has plenty of strange fish (and people) ?

Does anybody know what type of fish this is?

Welcome to the forum @Dakkta. The fish in the picture you posted is a Bermuda chub. They are a very common species of fish in South Florida reefs.
