Update
well, there has been no improvement, I am treating with Noxich which claims to get rid of ich and velvet. The fish is looking worse and showing a lot of tattering on the fins too. But I noticed Nozich does not have any copper in it, but it is what I had on hand. I also only use half a dose because my fish store did not know how my rope fish would tolerate the med. And I forgot to say that I have not added fish since proably Dec. I need to update my signature because it is all wrong now. The problem is in my 37 gallon tank which I started with a fishless cycle and added a full load in Nov - 1 opaline gourami, 2 dwarf gourami, 1 rope fish, and one snail. With in a week one dwarf showed signs of ick. So I bought the medicine, but the fish died the next day. In order to rid the tank of ick, I treated with heat and salt. I lost the snail. I was feeling very depressed about the tank. Then some time after the heat/salt treatment, I added 5 otos to take care of the algea - all appear healthy and active. Then the opaline got some kind of problem in its gill and died. Now the remaining dwarf has this stuff that maybe is ick or maybe is velevet, but what ever it is he is looking worse. The rope fish appears healthy although he has a couple of dark spots on his tail that I am not sure if they are his natural markings or yet another problem.
