Photo ID: Dead & scrape or alive & keep? (Part II)

[amahler]

A continuation of my other post since I had six photos and only three are allowed at a time.

Again, names of things and indications as to whether they might be dead or not and should be scraped off (to help keep ammonia spikes down) would be highly appreciated.

Thanks!

Picture 3, that's an aptasia, need to nuke that one (don't scrape it), but every thing else looks fine to me.

Gerald is right on pic three. You don't want to scrape it or try to remove it cause it will spread. You will need to "nuke" it. Joe's Juice works.
Not sure on what is in pic one but pic two is a stoney coral Cladocora sp. It may or may not live but I wouldn't bother scraping it. The brown areas are areas that are still live.
