Hole in tail

[MaggieLynn]

I just established a sorority today and after watching them i have an idea of who the alpha is but i just noticed that one of my girls has part of her tail missing. there is a hole near the center. what can i use to fix this? i do have api stress coat api melafix and i have aquarium salt, the melafix says for damaged fins. do i add it to the whole tank or get a QT tank?

Put her in a QT tank and add some aquarium salt, 1 tsp per gallon. The salt will stimulate the production of electrolytes. Also use Stress Coat. And a high-protein diet. Once she's better, reintroduce her. When you first start a sorority, you'll have a WHOLE lot of ripped fins until they settle down.

Thanks!! I knew that there would be fighting but its been half a day now and they seem to have the pecking order down and its almost like how i predicted. My two crowntails are the most aggresive and one is the alpha and the other is like the second in line. Thanks for the help!

how often with the aquarium salt and what about water changes for the QT?

[Sakura8]

1 tsp of salt per gallon all the time, water change every day while in the small QT tank, redo the salt. Probably keep her like that for five days and if there's no improvement, keep her in there for another five days.
