do fins grow back?

Often they do if you give them great water quality. My parents have some tetras that have been living for 2 years with partial fins though. I would suggest doing good water changes and giving a good quality food.
 
my cories have been healing with lots of aloe medicen they were hurt in an argument with my khuli loach ofer the food wafers.:(
 
MelaFix is great for healing damaged fins.
