I'm not familiar with that silver perch but I have a suspicion the perch is the one who nipped your cories' tails. Any pics of the perch? Use Melafix in the meantime to treat their tails. Water change should be done as well to remove ammonia.

Is it possible as well that it's finrot? Often with finrot there is red ragged flesh on the fins, or tip of them.

I'm not familiar with perch either but I would doubt that the mollies did it if they have been nipped, which seems the most likely cause.

I have struggled to get photos on my posts it wont let me add them any suggestions of formats that work easier? Anyways i have tried to do some research as well on these silver perch and they were purchased as little feeder fish to see how they would go in the tank. Information suggests they are aggressive but these would be lucky to be the size of a tetra. With the medication for Finrot what medication would you suggest would be most effective and safest to other fish and will i have to treat the entire tank and for how long.

Thanks again guys you have so much information and so informative. I never ask the Fish shops for advice as the advice i get seems the wrong thing to do and can harm the fish even more they seem to be very chemicals solve everything. Thanks again guys such a nice place to chat about fish and share information and experiences :) :) :) :) :)

To add a photo, compress it. It took me a while to figure that one out.

If the tails are not frayed, but "gone" more of a nipped edge, then that's what it is, nipped. Do a water change and add some melafix pronto!


Pardon the pun, but I'm hooked!
