ok, so here goes. yesterday, everything was fine. tonight i got home to find a very interesting outbreak of something... no clue what it is. looks fungal? maybe bacterial?

it's a 75g tank, been running for years, no live plants, 2 cascade canister filters each rated for 100g. this tank is really just a homeless shelter where i house large fish that have either been brought to my house or brought up to a store i was working at in a bucket. no live plants, no substrate, just a couple pieces of driftwood and a couple ugly cave-type decorations i got for free.
stock list-
2 large oscars
1 14in RTC
1 12in albino channel cat
1 8-9in red parrot
1 5in jaguar cichlid
about a dozen convicts black/pink
5 5in silver dollars
1 8in featherfin syno
4 12in senegal bichirs
1 10in australian yabbie (giant crayfish)
regular water changes and overfiltration have always worked wonders for this obviously overstocked tank.. along with light feedings, i've been able to keep the weird group of misfit fishes happy, until now. nothing has changed in my routine. no new fish, plants, or decor. no different foods. nothing at all i can think of that could cause this. temp holding at 78 degrees, ammonia/nitrite both zero, nitrate at just under 10, according to API test tube kits. i checked, and the kits aren't expired or anything.
did about a 75% water change, dosed with jungle "binox", which claims to treat both bacterial and fungal infections. pulled the yabbie, just in case he's sensitive to the meds, he's now in a tank by himself. within about 15 minutes, most of the fish perked up visibly. all the fish seem to be affected to some degree, and this literally came about in less than 24 hours. the tiger oscar has a scratch on his/her face that is also new, i can only assume the yabbie got it, or it hit a piece of driftwood. this has never happened before. any ideas as to what might have caused this? i'm at a loss.
