3 day blackout - Question

[keddre]

I'm going on vacation for a weekend and was thinking about doing a blackout for algae while I'm gone. My question is whether any of my critters will be harmed by the blackout. I feel the answer is no, but I'm not 100% sure. Thanks in advance, SCI

Fish:
2 engineer gobies (trying hard to get these out without tearing up the tank, any ideas other than the failed bottle method?)
1 maroon clown
2 bumble-bee gobies
1 guppy
1 one-spot foxface
3 banggai cardinals
1 yellow spot watchman gob

inverts (probably forgetting some but you get the jist):
2 feather dusters
1 flame scallop
1 sea hare
1 tiger pistol shrimp
1 long spine urchin
1 long tentacle anemone
3 red Cortez hermits
3 blue legged hermits
1 turbo snail
4 asterea snails
1 tiger sand conch

Corals:
1 leather toadstool
zoas
assorted mushrooms

With all those lives in your hands, is a blackout really necessary?

Huh?

The only things that rely on light are the corals, and those corals are hardy and will be fine.

Lol, I think he meant with all my algae eaters. I just got back, a day early and so much happened to my tank. A chemical warfare broke out, so I'm going to petco tomorrow since I'm out of carbon.

Lastly, my female maroon clown stopped trying to kill my male
