I had one sick Gourami, now the other is also not looking good. They hover at the surface, looking like hypoxia, working their mouth and gills very near the surface. Water tests are all good. The tank is one month today, and just the past few days all NO2/3 levels came down nicely, I think completing the cycle. I don't know what it is. I think the water is very good. All the other fish are very healthy.
Here are some pics of the Guorami: http://captwiggum.com/fish/
Any advice appreciated.
