    Hey,

    I would try adding some salt to the tank 1 tbsp per 10 gallons and up my tank temp to 88 degrees.

    If things don't improve after that you might have to try medication but there are other folks on here much more suited to tell you what to try.

    Usually clean water, heat and salt can fix most things.

    Hope this helps.

    I’m with Tony. Raise the temp do water changes daily. Not so sure on salt yet. First do those things and see what else s recomended. Also vacume out your substrate during water changes. Everything your allready doing is correct but the temp. Bring it up slowly and see if anything happens as it goes up. Like 2* a day. Are those all 3 fish or just one? S there anything else in the tank? Have you added anything new?

    I vacuum the substrate every w/c. Only the 1 fish is affected. The only other things in the tank are a breeding cone and a small cave decor. I will raise the temp 2 degrees a day and daily w/cs and see the results.

    thanks

    Jim does the fish in question get picked on by the other 2 discus? Are the other 2 a pair?
    You mentioned what you feed, but does the fish pictured get/eat food? It looks to have lost a lot of condition down the lateral line. Perhaps from bullying at feeding time, perhaps it has internal parasites of some sort??
    If it's not sick, and just not getting enough food, a fix could be to QT then add a few more adult discus to your 72gal...

    the other fish are not a breeding pair. the sick fish used to be the one picking on the other 2, not much aggression in the tank in general. at feeding time, i stick 2 pieces of FDBW on oppososite ends of the tank../ the sick fish does get attentive at feeding time and will nibble the cube a bit, then go back to the corner.. i can qt it for a bit to see if that perks it up. i had planned on getting more fish,, thanks for the reply

    This is an update and an ask for advice. I lost the fish mentioned here last week. Over night, I lost a second fish that showed no sign of stress previously. I have 1 fish left as well as 2 green cories in the tank. My parameters are the same as mentioned above. Are there any other tests I should do to figure out what could happen?

    thanks,
    Jim

    I did not read all of this but do you have more than one tank where you could leave this one fish to observe it for several weeks? If you are going to add more fish you could buy from a forum sponsor at the ratio of 1 fish for each 7 to 10 gallons and keep them separate. By leaving the lone fish in the tank that it is now in you might learn if it is something in that tank that is causing the problem. Or you could put all of your fish into another tank and then tear the tank down, sterilize both it and the filter replace the water and put the fish back in and then see what happens. Just a thought but not sure if it would be a solution.

    Thanks for the reply. i am leaving the fish in this tank, doing daily w/cs and watching its behavior. so far the fish is acting normally. i will also slowly start changing my bio media for new media. the media i have i haven't changed in 5 years. just rinsed in tank water once every 2 months. i have 2 eheim 2217s on the tank

    Jim you’ve had these discus for 5years? Just strange for this to happen after so long. The first discus pic the fish has a divot in it head. Was that always there? Do you have a uv steralizer in the tank? I never change my bio media. What are you using?

    The divot was there for a couple of years. it never got worse, so i didn't think anything of it. i do not have a sterilizer on my tank. i am using eheim substrat and seachem matrix

    i just thought of something,, i have a brute barrel that i use to age my water. i have not cleaned that since i got it. 4 years ago.. since i dose the tank when i do wcs, is it possible the barrel has some contamination in it from the municipal water system?

    Jim I have heard of people getting a slime build up in their aging containers, but I'm not sure of it can be attributed to disease. The chlorination/chlormination of municipal water is to prevent pathogens from passing through the system to the end user. I would think that anytime you refill with fresh municipal water the chlorine would act as a cleaner in your barrel, but I would be happy for my hypothesis to be wrong or disproven. Let's see what the community has to say...
