How big is your tank? How many tetras do you have?
Do you know your water parameters? What is your water change schedule?
Yes fins can regrow if the water conditions are good. Add a bit of aquarium salt or stress coat will help.

It'll grow back. Just do regular partial water changes so their water is as fresh as possible. Maybe treat with an anti-fungal, too, though it's not necessary if you're not seeing signs of fungus, yet.

That seems a bit unusual for glolights to be that aggressive to each other. How many are you keeping and in what size tank?
