I have to add my experience though it's a little different. I have a Rhinopias and everyone and their uncle said you can't have tangs, angels, and foxfaces with the Rhino. The tangs, Angel, and Foxface will constantly pick at the Rhino, Blah , blah, blah. Well I did it anyway and the Rhino is now 6 months old and nothing messes with the Rhino. The Foxface did once and the Rhino reacted and he knows now that the Rhino is not a piece of algae for him to eat. I'm tired of everyone sticking to a yes or no answer when it comes to compatability. Each case will be different except for the obvious ones, (i.e. 2" clownfish with a 7" Lionfish), though I bet they have lived happily in a tank together. Most importantly have options if you do try to add the Puffer with the Frog. Have a seperate tank set up. Set time aside to watch the fish interact from a distance for long periods of time.
