Molly Fry Missing her Tail Fin...

[saa5886]

I just noticed today that my molly fry is missing her tail fin. She isnt showing any signs of being sick, and neither is anyone else in the tank. Shes the only one with any issues. Any idea on what this could be?

one of the other fish could have nipped it off...what other fish are in the tank with the fry?

 

[saa5886]

Shes actually completely by herself in one of those breeding nets...

It could be fin rot if there is no other fish to nip it off.

but why would it happen to only the tailfin and why wouldnt it happen to the rest of the fish in the tank? all her other fins are perfectly intact..

Fin rot just happens, doesn't have to be all the fins. I have some fish who only had it on their pec fins, and my bettas only had it on their tail fins when I got them.
Clean water is the best medicine.

Well, since my tank has cycled a couple weeks ago, I've done 2 water changes and cleaned the gravel once (less than a week ago)..
I'll do one more water change and add more aquarium salt..

Sounds like a good plan. Good luck.

Also, if it keeps getting worse, you might want to try Melafix.

Well, the fin is totally gone... I thought they were supposed to die when their tailfin disappears?

 

[dkpate]

Well, sometimes they can grow it back, it just depends on how bad it is. Can she still swim?

Yeah shes acting totally fine.. but her fin is totally gone.. its weird.

Well, just keep the water clean, cross your fingers and hope for the best.
