baby bushynose plecos with broken pecs

I received a shipment of 5 baby (1 1/2 - 2 1/2 " albino longfin bristlenose plecos recently. When I released them into their QT tank, I noticed that 3 had broken pecs, pretty far up the bone (close to the body). This morning , 2 that had complete breaks, the broken off part of bone is gone leaving them with a short fin on that side, the 3rd, still has his bone attached by the fin.
I've added salt to .1% and Melafix. Is there anything else I can do? The ones left with short fins, will any of it grow back?
Thanks!

wanna see pictures...

It's possible that the fins can regenerate, but even if they don't the fish should be able to survive in an aquarium environment. The best thing you can do for them is provide clean water and a chance to recover. Any sort of medication risks producing side effects for all the aquarium inhabitants. Many times, partial water changes are more effective.
