Death of red tailed shark

[Litespeed]

We are battling ick which is on our pictus catfish, no signs of ick on the red tailed shark. We just performed a 50% water change, trying to keep the water temperature as close to 85 as possible during the procedure. After filling the tank back up we noticed that our red tailed had just died. My flower garden is becoming a cemetery for fish. Usually we only do 25% water changes at a time but since we have the ick and the nitrates had risen to 40 we decided to do 50% this time. Could the stress of the water change have killed him? I'm about ready to give up on aquariums all together. We keep trying to do the best we can for these little guys and it looks like we are losing the battle.

Wow, I'm really sorry to hear about all the stuff you (and your fish) are goin through. I had a major bout with ich before, and I lost my fish. After that I decided that was it, no more fish! So I didn't have any for several years, until I decided to give it another go. Luckily, my fish have been doin well for over a year and a half now! **knock on wood**. Good luck, but dont let this discourage you. Every says how each Ich is to cure, but the 2 times my fish have gotten it, they didn't fare to well. Keep up the good fight!
