this past weekend i noticed my biggest rainbow having some very small white specks on his tail, as well as another one of my rainbows. it looked similar to very tiny grains of salt. i thought ick, so did a water change and added coppersafe. i checked the next day and the smaller rainbow seemed to be better (if i look close i can see maybe one speck), though he is not acting like himself, hiding but on the outside he seems to look pretty normal.
yesterday, i noticed these white small splotches on the big rainbow (as shown in the photo, though not clearly), today they have gotten a lot worse, as there is a lot more of them and are very visible when he's directly under the light. none of my other fish seem to have this so far. does anyone have a clue of what it is?.
also, recently i've had had to euthanize a few fish. one was a golden barb that had this red ulceration on his side for a couple of months and it was not getting better (i treated him once), it did look fine at one point but opened up again. also, another rainbow seemed to be looking pretty bad and started to have what looked like hemoraging near his tail and then one of my danios had it too. none of the other fish have gotten it since then and what the rainbow has is not what they had.
i have also had really bad luck stocking my tank recently too. i bought about 5 cories a few months back and all died within 3 days. i acclimated them over a couple of hours too. but that was a few months back. and just recenlty i bought an angelfish and it died the next day, though to tell you the truth, it didn't look so hot to begin with and i think the stress of the whole move did him in.
i have a 55 gallon tank which currently has 5 golden barbs, 3 black skirts, 3 rainbows and only 2 danios (since they have died over time).
i just checked the nitrites and they are at 0 (so i'm assuming so is the ammonia) the nitrates are a little below 5.
anyone have any ideas at all? i am getting really frustrated with my tank. i've had it for over a year now.

here is the photo of the rainbow

That definitely looks like ich. Ich can be on the fishes' skin and not visible for a while, so this could be why you see new spots after adding meds. Wait a few days and see if there are more spots or more fish with symptoms. It can take a while to cure ich, as it can only be killed when it's freeswimming, not when it's on the fish.

It would be a good idea if you can set up a hospital/quarantine tank if you want to add fish, to avoid bringing diseases into the tank when you add new fish. :)

do you really think it's ich? the stuff towards his tail looks like it to me (not visible in the photo) but the stuff all over his body doesn't look anything like grains of salt. it's a lot bigger and looks smoother, almost fuzzy but not. very hard to explain. and wouldn't the whole tank have an outbreak of it?.
i've seen ich in pet stores and what he has looks nothing like that?.
