[tony_3a]

the black spot is only on one side of the tail not the other. Ill try to get some of that garlic stuff maybe oceanic has some in i am going there tomorrow. Thanks for all the help. The shaking does appear to be from his head mostly not his whole body, to feed him garlic do i need to make sure he is the only one eating it, or is it ok if the other fish eat it as well? The damsels eat like pigs.

Also i have a anemone as well, but he is hiding under a rock i dont really know how to feed him, the nemos are hosted by him tho i saw that they can bring him food or something.

More pics can be found in my tank journal i just started one.

Thanks a lot
