Great to see!
Another trick I used to get fish onto different feeds from stuff like bloodworms, tho I don't know how well that works with a larger cat like yours, is to put the known and new food into a shallow glas (or any other heavy container) and let it sit a bit before you carefully out the glas in your tank. That way the feeds sit directly on each other, exchanging tastes and the fish will inhale both when feeding. And the feeds don't flow around seperating. It worked for me with a lot species, including electric eels, I just never needed it on a cat before.
