how to tell if sps are dead?

[Drake1]

i had a huge purple sps colony bleach white then turn brown, i assumed that it was dead, it never had polyps so it is hard to tell if it was alive. i took it out of the tank one night and it was slimy so i put him back in. is there a better way of telling if he is live or dead?

brown is still alive. WHITE is dead. browning tends to happen when the coral's not happy with it's current location. mainly deal with lighting...

If it turns completely white it won't come back. After being dead a while in the tank algae will grow over the skeleton which may be what your seeing.

I got a frag from a friend that bleached out fell to the bottom of my tank and stayed there for two weeks. Just when i was about to take it out i noticed it still had polyps. To this day its one of the best sps i have.

do sps build slime on them? i've always been a sps guys should i try and take it out again and see if it slims again.

I think the best way to tell is you can first see the white skeleton and then algae grows over it. I almost pulled out a ora Hawkins which I thought was dead and it was looking very ugly with no PE even at night. I let it be because and it has now maken almost a full recovery and is turning blue/green and has pe again.

Ive got a monti digi that was accidently fraged and i put it in a cycleing tank. turned snow white but still has polyp extension just like the mother colony. I dont think its dead.

I have had SPS go white and bleach with polyps still out. Left it alone and it is coloring back up. Leave SPS alone. They need stability. Don't move them for weeks. Especially if they are turned white. Constantly moving SPS and some other sensitve corals WILL kill them.
