This is my first post ever and what do I bring to the table...a gonapora problem. The first three weeks were wonderful, the gonapora was looking magnificant, very healthy looking and I even moved him once to a better place in the tank and still doing great for several more weeks. I am pedantic about the water quality in my 90 gal tank. I have several fish as well as 2 shrimp, one a cleaner shrimp, the other a blood shrimp, neither one goes near it. I have compact flouresant lighting though. I plan to purchase metal halide lighting when I can afford it and maybe even a chiller to keep the temp stable. Anyhow, the darn thing has closed up and only seems to want to open only about 1/4 its full extension, there is no apperant slugh-off or discoloration of the membrane, no slime or die-back. I feed it only the best phytoplankton (PhycoPure) and try to keep the temp and calcium,as well as salinity and SG in the normal ranges. Can anyone help me understand this creature better, I would love to see it healthy again.
