Something's wrong with my Aquarium fish!?
When i bought my fish, they were all fine and healthy. I gave some to my brother-in-law, which several of them died soon after wards, he took very poor car of them.
They were half or fully blind, but i "healed" them, until they seem completely normal: swimming well, healthy diet, no white gunk on the eyes.
But when i mixed it into my bigger aquarium, about 6-7 feet long, at first they appeared just fine. Then they began developing these weird black dots? It looks like someone took a black/grey gel pen and started to make dots between their eyes and to above their mouth.
Then they start having trouble swimming, and some of them is so bad with the disease they just sink onto the sand. When they try to swim, they look like something is pushing them back, like a human wobbling almost.
I have 4 Pleco's around 4 inches big now, they are fine, my angel fish bought on the same day are fine (5 of them), it's just my Discus fish! i have 15 of them, and 5 of them have the disease heavily, and 2 of them started to get spots on their face!
The common symptoms:
-Rapid breathing
-Black/Grey Specks between eyes (commonly on face)
-Trouble swimming
-Trouble Eating
It's spreading! i don't know what disease it is, it doesn't match anything on the websites.
I love my fish 
please tell me what's wrong with them?
My eldest Discus is about 5 years old, i take great care of them, but i don't know what's wrong! I know it's not my aquarium tank, it has an amazing filter, it was suitable hiding spots, there is no water worms, no parasites, nothing! And it can't be the food, i've been feeding them the same product ever since i bought the fish!
Please help me.

All these symptoms make me think that you are dealing with an excess ammonia problem. Ammonia will lower the oxygen in your tank. It also makes your fish listless and not hungry. It will burn your fish's body which can explain all the dark spots you see.
How big is your tank in gallons? I suggest you perform a 40 % water change and see what happens. Also do some research online on the type of fish you own and their space requirements. Remember that some fish might need a bigger tank as adults. Get a test kit to see if the ammonia levels in your tank are safe….

Just take the fish that are fine out of the tank that has the disease in it until you find out what's wrong.
p.s my sister fish had most of those symptoms (not the spots) and it ended up that her bigger fish were eating/ attacking the smaller ones.

separate them. you may find that it is gill fluke. http://www.aqua-fish.net/show.php?h=discusfishrevision is a good source with information on the medication of that and a variety of other conditions that can effect discus.
hope this helps

normally when the fish get cloudy eyes it generally means that the fish has got serveir whitye spot but theblack / grey specs on the face is also a type of parrasite called a dinoflagellete protozoan and is treated the same way as you teat white spot

I did a little research for you, and it sounds like it may be what's called "Black Ich" or "Tang Disease". They are a type of worm-parasite. I've included a link, and REALLY hope it helps; good luck!

Were the discus newly bought? If so, do you happen to know if they were tank bred or wild caught(you may be able to call the store and ask). There is a "disease" more of a parasite, that can cause black spots. It's more common on wild caught fish or fish that are kept outside in ponds. The life cycle of the parasite is a strange one, goes from something like birds, to their droppings, to snails, to the fish, etc. And I don't remember what parasite it is exactly, maybe a trematode(?). Not a whole lot of info out there on it either, and the links I had, I lost when my computer crashed. But, try doing a search on black spot disease in aquarium fish, and look for the links that make reference to a parasite infection, not anything else.
Discus are commonly wild caught. Sorry can't give more info then that, but try that search and see if that matches the symptoms you've seen. Good luck!
