Yeah...I understand about the lights, and thanks for all of your feedback Colin. When I turn my lights off, the oxygen pumps out, so that was primarily why I was doing that. I had also read a superstition that Ich has difficulty 'finding' the host in dark tanks (didn't really belive that one). All signs of Ich are gone, but my gourami still has pop eye (I am continuing with Ich treatment at high temp, and I will do one or tw more days of dosing anti-bact.). BUT, I lost my festivum cichlid this morning, to an unknown cause (My favorite fish!). He did get stuck in the crease between my Easter Island ornament and a hole in my driftwood, but I don't know that this was the cause of death. I could see no visible signs of infection, but he had been looking rather sluggish. To make matters worse, a hurricane is headed our way. I do have the necessary aeration equiptment if the power is to go off, but considering all of the problems I am having, this is a really bad time for this threat. I am going to dose the tank for a few more days, followed by daily 25-40 percent water changes daily for a few days. The only good news...a new LFS has opened near me, and it is very convenient. The staff is nice (not arrogant!), and the owner is an incredible looking young woman. You have to find the positive wehre you can when your fish are dying...lol.
