I have a group of four C. panda in a tank that seems to be infested with some sort growths, mainly on their caudal and pelvic fins but it also seems to affect all the other fins and occasionally the barbels. Please see pictures below.
Photos:
The male has been in the tank for months, the three females were moved from a larger tank a couple of weeks ago from a larger group to breed with this specific male. They spawn every 3-4 days at the moment. A new piece of java moss and a water lillie was introduced also a couple of weeks ago. There is a possibility that they were overfed over Christmas when i was on holidays but I did not see any traces of this. I thought that they would need to be stressed or damaged for something like this to happened, could the move from the larger tank and group have caused this?
There is also a fry box with plenty of eggs floating in the same tank, should these be removed prior to medicating the fish, would moving them to another tank risk spreading the disease?
My thought was that it's fungal/fin rot but I would really appreciated your advice on what it is and how to treat them.
