Last night I bought 10 more pounds of LR
from the LFS
and put it into my tank. I did a little re-arranging of the rocks there to start making it look nice. The fish just checked me out and went to the other side of the tank.
Later on in the evening I was looking at the tank and noticed that my Domino Damsel was acting strange like he was frightened. He normally is the "bully" of the tank and swims all over like he owns the place. I didn't think much of it at first because when I put the first rocks in a week before they all did the same thing, they seems kind of scared. A couple hours later they were back to normal.
But, on this occasion, I noticed something different with the Domino. He seemed to be "breathing" exceptionally heavy and staying put behind a plant. I went to bed and at 3 in the morning I got up and went downstairs to check on him. I turned on the light and found him towards the bottom of the tank kind of listing onto his side. I though "Well, when I get up to go to work in a couple hours I will remove him from the tank." I thought he would not make it through the night.
When I got up to go to work at 5:30 I checked the tank to see if he was OK. He was back to being behind the plant but in better condition than before. I called my wife at 11:00 today and asked her how he was doing. She said that he was swimming around a little but not his normal self.
He did not eat when she fed the others this morning. Usually he gobbles up most of the food. He is still acting very scared.
I checked all my readings this morning before work:
They all seem to be normal readings don't they? What could have caused him to act this way? Thanks in advance for any help on this. It just makes me feel bad, because I put those fish through hell during the "cycling" period and they survived. I want to keep them alive. they are my buddies now. Part of the family.
