I'm glad the red streaks are getting better!
I never heard of chloramine-T; here's a link that I found:
http://www.algae-control.com/chloramine.html It does say that bacterial gill disease and flukes are eradicated. I have a med from Mardel called Mar-Oxy that contains stabilized chlorine oxides. It may be similar to your med. When I bought it the
lfs person said don't bother buying it and just add some tapwater, untreated, to the tank. I didn't do this because I didn't know how much tapwater would be enough or too much. Here is another link that says the chloramine-T breaks down to release chlorine and oxygen:

If you use this med, run carbon and do water changes to remove the Aquari-Sol. Be careful of too high of a dose; according to the link it can burn the "skin" so follow dosing directions carefully. Do you think that the Aquari-Sol or the heat didn't help? Does it still look like his gills are affected or he needs more treatment? I wondered if the heat plus the Aquari-sol would be stressful at the same time and that's why I recommended the half dose, and especially since he's scaleless, but it makes sense that a minimum concentration needs to be maintained in the water. Remember also that the ich parasite is only susceptable to the meds for a portion of its life cycle. There are copper test kits available. Here is one from Red Sea. It is for a marine tank, and I don't know how valid it would be for a
FW tank. If you were interested, you could probably e-mail the company and ask.

There is debate on whether the ich parasite always resides in the fish and becomes active if the fish is stressed. You could do a search on the forums to read some of the ich threads. I don't think the ich lives in the water and only infests the fish if they are stressed. The ich can't live without a host, so it couldn't live in the water, and not on the fish, for any length of time. I don't know either about the ich living in the fish, but only causing an outbreak in stressed fish. Some say it's true but I have seen nothing to back this up in my tanks at all. Either it's not true, or my fish have not been stressed in two years, which is great too!
Well, I guess I started rambling, lol...See how your fish is doing over the next few days with daily water changes and finish your Aquari-sol dose, then re-evaluate to see if he needs more meds. Hopefully he will be ok, and not need any more meds.
