Hello; This.A few more details please.
What size is the tank?
What fish are in the tank? How big are they?
How often do you change the tank water, and how much do you change?
How much do you feed and how often?
What foods do you feed?
Do you own a test kit? If so what is your ammonia, nitrite and nitrate levels?
Have you added any new fish, plants, rocks or wood recently?
Did you clean/quarantine any new additions?
Hello; This.put into a quarantine tank
treat with methylene blue and Seachem Kanaplex.
Hello; Some suggested treatments in QT but not sure what your response is so far. Before any other suggestions it will be useful to know the steps you have taken. Not clear you have done anything at all yet.plain salt 1tsp per gallon and what rocksor has mentioned.
Hello; You can see the fish in person but these photos were not much help.I just went to check and it seems like shes getting better
Hello; This.named quite a few fish that have the ability to cause damage. I would say ever single one you listed
Hello; OK, I guess you have it figured out.Not however the damage caused because it all seems to be internal damage. As said before , no cuts nor scrapes can be seen. So unless one of my fish can do damage on the inside of a fish, i was right.
One of the other fish easily grabbed that fin, and pulled it. The other poly can do that with no problem. Hence the damage shown in the first picture, and the additional redness in the other pictures.Not however the damage caused because it all seems to be internal damage.

Bingo !One of the other fish easily grabbed that fin, and pulled it. The other poly can do that with no problem. Hence the damage shown in the first picture, and the additional redness in the other pictures.
