I would stock different fish in each pond. What type of fish do you like to fish for?

If it were me I'd do one pond as a LMB/Sunfish pond and maybe the other pond as a SMB/Yellow Perch pond.

That way you can have different fishing experiences at each pond.

But wait for an expert opinion, I'm just an idiot with a fast keyboard.
