Does it look like fin rot with the red streaks in their fins and near the base?

Well if it's hard to tell, then it might not be. Other fish may be nipping at it or what have you.

I've had fish that grew back their scales, fins and tails, but it grows back very slowly. From my experience, tails and fins grow back a lot slower than scales do.
