No the toadstool was not quarentined, I don't know that I've ever heard anybody mention quarentining corals. I could see why that would be wise though.
I have witnessed a little agression, the starry blenny likes to seat himself in the toadstool, and on the clam and etc. he thinks everything is his personal throne. Although I've only seen him pester the wrasse, who's a good 5" and doesn't seem terribly bothered by the blenny. I kind of suspected him as well.
The male didn't show ANY physical signs of illness, but he did exhibit loss of weight, which is cause of suspicion for an internal parasite, although it seems that this type of slave/master relationship is regular of breeding clown fish. The female is exhibiting something completely different from the male though. Her slime coat seems a little thin, not like I can tell until I can look under a microscope, but scales look a little more shimery. If she turns to one side and then back you get a flash of white reflection from the scales. Not like shes flashing sideways like a goldfish. The gills have a ragged but patterned appearance, she is still eating though.
Yes I soak flakes and pellets in selcon twice a week also, no I don't refrigerate it, but not a bad idea, these are both less than two weeks old, I'm gonna go stick them in the fridge. Thanks for your insight btw. Where do we go from here though?
