Couple of days ago I put a dozen baby gold fish in the pond. Today the frog in the photo discreetly hiding behind the post. Should I remove him?

Should be fine. The goldfish will be too quick for it to catch if it tried. 

 

They usually catch prey that is crawling on the land or plants near the pond, or bufs that fall onto the water surface, rather than catching prey under the water. 

 

It will be good for eating garden pests.

Yes, correct. I changed my mind after a second close up look.
