For the second day now my catfish has had some type of disease or fugi or something externaly. In the evening i noticed it swimming around rubbinb its back a little, there were two sores. The next monring i noticed two more sores and his fins and whiskers were rotting/eaten away. Later i had a small pleco die with no physical indications.

Since then i have done water changes, cleaned spounges, added melaflix, tiny bit of salt. adding a heater to tank right now as i type.

As of currently the sores on the cat aren't spreading or getting worse, and the whiskers dont seem to be getting worse. But one sore looks deep There is a picture below.

The catfish is a marbled catfish housed with an ATF, sabertooth tertra, marbled goby, rapheal cat. This tank is connect to another 80 gallon with a leichardti in it. Then in the sump ther is an albino bichir and south american lungfish. None seem to show physicaly issues, just the ATF has one cloudy eye, but prob from banging into something in the tank. I dont want to do anything that could harm the other fish.

I noticed a lil while befor the cat got sick that the fish that usually eat the raw food, ate less then noraml and now they dont eat much. And also i would add feeders (because that is all the sabertooth eats) to the tank and a few days before the sickness came there were more dead feeders in the tank then usual. I was guessing the ATF was killing them but maybe it all has to do with the water condition. Ive had internal parasites years ago and nothing else serious.

Anyone have a good guess on what is it? so i can specificaly go at curing it?Pictures ofcatfish below.

The red box is of the sores. The yellow is a lil skin rash or skin coming off, just a tiny bit. The blue is the upper fins rotting. And the orange is of the whisker that was eating or rotten away.
Thank you for your time.
 
Not sure yet. So far from looking over the fisk i believe it is a type of fungus. The fin rot is present on one fish, i can see what looks like to be small blotches of fungus on the head of the catfish, one fish has a lil eye cloud, the the sores are healing in some places but starting in other.
I tried using API fungus cure (which turns the water green!) for the past two days. With the increasing of the temp of the water and adding just a little sale (i think salt might be bad for some fish like my lunfish) ive noticed the catfish becoming better. Then when i added the API i noticed it seemed to clean up the catfish and stop the sores and all. But then it seem to spread more again. And now its seemed to calm down more. But still serval sores and some what looks liek fungus on its head. Ive taken out the carbon and continue to raise the temp some. Not sure what to do next. Going to start doing 25% water change as the API says to do after using it. And prob clean all the media.

Any ideas?
