ADFs normally will leave others alone unlike the ACFs. Please do not confuse the ADFs and ACFs. ACFs do not have webbed front feet and ADFs are not available with albinism trait which ACFs are often sold as.
Yeah, I was at my LFS couple of days ago to buy some neon tetras (put them in my 10g tank which will know be used as a Q/Hospital tannk) and they had albino african frogs (they didn't put the word "clawed" in there, probably too scary for kids), but they were obviously ACF and not ADF. They had some smaller and non-albinos in there, but I couldn't see webbing on their front feet, so I didn't buy em. Because as you said, ADF have both webbed front and hind legs.
