awww blue....dont be blue....LMAO anyways....its fine, i just thought..since he's new to it...probably shouldnt put more ideas in his head til we figure out ...
I think the first thing we need to do is get the tank cycled. At 3 weeks old your almost certain to have both NO2 and ammonia (NH4?) and that is likely what is killing your fish. Don't fret, it can be done with fish as many have done but you do need to do some water changes regardless of what your test results are. At least 10% every other day if not every day until the tank has completely cycled, about 3-5 more weeks on average, 6-10 weeks total. Keep up on the water changes and we can at leats get you to a point where the water is safe for the fish. If you absolutely can not do water changes that often then 30% twice a week is at least enough to try and help keep the levels down enough that they aren't as toxic to the fish. At the absolute very least, 50% once a week but that is stretching it and most likely causing major damage to the fish.
The way the fish died sounds like NO2 poisoning but could also be from ammonia. Red gills is ammonia toxin signs I think, not sure what signs is from NO2, fish disease is not my thing and I have a lot to learn about it. Thankfully I haven't had many problems except ich.

You lucky git, I had problems with columnaris before(last July). So frustrating and it wiped out my praecox rainbows.
I haven't had ich for almost 4 years straight(not counting 2004-2005 where I had keep a low profile from the hobby due to hectic schedule).
