its the ventral/pelvin fin
any advice please?
Fin rot is usually a result of poor water maintenance. Clean, warm water is the best for mild cases. A little more progressed case you can use 1 tsp of aquarium salt per gallon. A severe case you would need to medicate. If you can pick up some Stress Coat + it is great for encouraging the growth of healthy new fin. I would try warm, clean water with Stress Coat + (Stress Coat is a water conditioner in itself so no need for the Top Fin too). If you notice it getting worse, add the salt (but no more than 14 days of treatment). If it doesn't get better, or gets worse then post on the disease forum and people can recommend medications.
Also, check out OFL's water change recommendations for the size and type of tank you have.
