So I got these guys about two weeks ago, no improvement what so ever since then. I just picked up 3 more fish this weekend and put them in QT with these guys and it spread to them as well (I wanted to test if this can spread as others say it can't). So is this really black spot disease or something else since it has spread to the new fish without the presense of birds? What should/can I do?

Perams:
Stock = x7 wild caught Columbia Satanoperca
Tank = 55 gallon bare bottom/x2 Hydor V sponges (fully cycled)
pH = 7.6
Ammonia = 0 ppm
NitrIte = 0 ppm
NitrAte = 0-10 ppm (0 ppm most the day, 5-10 ppm after 10pm at night)
Temp = 88 degrees
Water change: 50% / day via drip system
Food = 2mm NLS twice daily

Try copper? Since they are in isolation it shouldn't be a big issue.

I am somewhat emotionally invested in these maps so I'll chime in. Does anyone have any personal experiences (good or bad) with either SeaChem Cupramine and CopperSafe by Mardel Labs?

Not too sure on whether it's black spot disease for sure, but have you tried adding any salt at all?

Yes, 10 tablespoons for the tank volume. I have stopped adding it the last week though since there was no signs of improvement. I have 40 lbs so I can keep going no worries.

I have not. Can you explain why I should and what it does? I literally know nothing of medications andf their uses. Why would it matter if they are in QT using copper may I ask?

Thanks bro. You saw yourself last night, they aren't really doing any better and it has 100% spread to the new maps. Looking forward to hearing the answers to this as well.
 
Looks like diplopstomiasis to me. These spots are larval trematodes. Usually not harmful unless the fish is weak or extremely covered. These parasites do cause some blood loss. This is fairly common from fish raised in earthen bottom ponds. Successful treatment is usually with formalin baths and increased maintenance of the system. High salinity salt baths can also eradicate the parasite. Formalin is the treatment of choice but, keep in mind that formalin is a carcinogen so, gloves and apron/splash guard are good precautions to take when handling formalin.

Somehow these black spots are surviving the life cycle without the birds or mammals. Would you recommend using Formalin first and then some form of Copper or vice versa?
