Rescue Guppy

[Sitchy]

I have just rescued a male guppy from a friends tank. I offered to take him because my friend had lost his two other guppies due to fish attacks. My friend brought the fish up to me today and it is missing a large proportion of its tail (will try to get a photo). It is very active and doesn't seem to be to bothered so i have my fingers crossed.

Will its tail heal and grow back? what can i do to help it recover?

Any help welcome.

Edit: Added photo

Clean water, melafix and pimafix. The trifecta of fin healing. It may not grow back if it has already scarred over or was damagaed at the base but I had a guppy that lost most of his tail twice and it grew back.
