Hi all. I have in a 20g reef tank 2 false perculas. They are unmated, but I had purchased them at different times, with one purchased at about 1" long, and did not really do a lot of mating rituals with the other. I used to be able to tell them apart, for one was more active. I cannot now. Anyway, I noticed at last feeding only one of my nemos went for the food. One did not. Yesterday, One of my false perculas hid under some live rock alll day. He still went to his sleeping area, though he just did not swim around as much. Today, the same thing. He is tucked between some live rock about 1" from the seabed. He seems to kind of tip here and there. He is breathing a bit heavy, but I've seen worse in other fish. My H20 parameters are: Ammonia-0 Nitrate 10 ( It won't go any lower) Nitrite -0 Phospate .25 (from tap water), ph8.7 and steady. I do not test for Ca
yet. I also have a duncan that has not opened in a couple of days. My tank has improved, in my belief. I have not had a sick fish in my FW
for quite some time. I added a sump/fuge about a month ago, and have increased my CUC. I have looked up many diseases for clownfish, and none seem to match. He has no discolorations or lesions. The only thing is his mouth is open most of the time. My other nemo has that cute frown, with his mouth closed. Thanks for any help you can give.
