Fin Rot

[Tonytheeagle55]

Hi

I have just lost my second Molly to fin rot some months apart, in that time I have not introduced any new fish, so where does the disease come from?

In both instances, as soon as I noticed the fin rot I put in a good treatment, the fish recover to the point where fin rot had recovered greatly and the fish seemed active and healthy, but in both instances the Molly's died?

None of my other fish showed signs of fin rot, so what's happening please?

Any help please?

Some more data would be helpful Tony.  "Fin rot" may be just that, or it may be due to fin nipping, or in the case of mollies in particular it can be due to the water parameters.
 
What is the tank size, and what fish are in it?
 
What is the GH (general hardness) and pH of your tap water?
 
What exactly is the "good treatment" you used that seemed to help?

Thanks for getting back to me.

The fish tank I have is 4' long, I have a couple of pleco's two Parrot fish, gouramis, Angel fish, Red Barbs, Silver Bala and Red tail Black Sharks 2, White Molley, 2 Banded Leporinus and my culprit if fin nipping is the cause, a Peacock Zebra Malawi Chchlid, but having observed my tank I have never seen this, Although it does occasionally ' pick on' the Parrot fish!

I am unsure of my water Gh and PH is 7.5.

The fin tot treatment is Inerpet Fungus and fin rot treatment as recommend by my aquatic centre, my black Mollies showed signs of both.

I hope the above is of some help?

The GH is crucial to know, before even acquiring fish, and mollies will usually not last if the GH is not moderately hard or harder, and fungus plus white edged fins with fins ragged and reduced in size (same symptoms as fin rot and fin nipping) is often part of this.  However, mollies can also show these symptoms from shear stress, and I can assure you they will be stressed in this tank with these tankmates.
 
Moving to the other fish, there are several possible fin nippers here.  I don't even know where to start, as this combination of fish is very problematical.  Many of these should never be housed together, and that is likely the real problem.
