I've had my 40 gallon tank up and running for about six months. I started the tank by getting everything from my lfs' tanks (live rock, sand, even the water) so it would cycle faster. I have a clean up crew, several corals, a bta, 2 clownfish, flasher wrasse, and a green mandarin. All of the livestock are healthy and doing great but I can't keep an angelfish alive. I tried a flame, it died in a week. I then bought a potters and it just died today. It lasted about 3 weeks. Both Angels had ich on them when they died. Water perimeters are perfect and temp is at 78. No other fish has ich or ever had it. How did the Angels get ich and the other fish not get it? They were eating and doing fine one day, then the next they get ich and die.
