thanks for the replies eveyone.
Duke, I have the wirey chaeto in my fuge. I thought chaeto doesn't go asexual, only calupra? New pics are less cloudy.
qy7400, I used to have 3 fish in there before I sold one and got 2 more, bringing the total to 4 fish. I don't think that was a huge change. I didn't purchase any more corals at the time either.
thanks for the offer keith. As of now, I'm ok on carbon and RODI!
Marteen, I do not dose anything for my tank. Only water changes every week (using reef crystals).
I don't believe my heater was the issue tommy, I have two thermometers in the tank, one digital and they both read 80 degrees. Maybe while I was at work something happened? I don't know
I figured out that the two picassos died from oxygen asphixiation. It's interesting to note that my other two old fish showed no signs, perhaps it was the stress of shipping that did them in...
When I get home, I will take new pics and make some new water for a 20% water change tomorrow.
once again, thanks for all your support!
Don
