Will these corys fins grow back

[16gallontanker]

I have 2 sterbai corys that have dorsel fin damage so my question is do yall think they will ever grow back? here's a pic of one of them but all the rest of my corys fins look fine

It should grow back fine. Keep the water extra clean to help prevent infection

If the fin rays are still there the fin should recover. It might not grow back perfectly but they usually grow back as long as the fin rays are undamaged.

this might be a better look

I would say chances are good, because the base of the rays is still there. But t really depends on the damage, and I'll take the chicken's answer and say that will simply need time for an answer. What was the cause?

I have no I idea

A couple of times, I have seen deformed dorsal fins on Cory group fish, including on sterbai once. The entire tank had tiny dorsals in the same odd shape, so that said bad breeder work. A friend had some and the dorsals didn't grow normally, but stayed small.

It could be injury, but unless you bought them sight unseen, that would be something to avoid in making future choices. They would still be great fish, but the dorsals on the genetic problem ones seem to stay odd. They always reminded of guys wearing hats that were too small for their heads.

Hopefully, something bit them and didn't destroy the rays. If not, it doesn't seem to weaken or harm the fish.
