It looks like it still has a bit of color on some parts. Hopefully you can get it to recover. Good luck!
I would start by asking people to only post if they have kept a S. gigantea alive for at least a year in their tank. A lot of strange suggestions in this thread; I'm not sure that all of these suggestions are coming from people with any experience with this species.
Then I guess -- according to you -- that I shouldn't post in this thread, since I have never kept a Gig. :thumbdown
Raw shrimp from the deli works also, just remeber to buy non cooked one if you go that route.
Todd please purchase a gig
I would like to hear from you .
From my mistakes keep the clowns to a minimum or babies .
My big maroon pair destroyed one of mine.
Over playfull in and out tearing it apart not getting any time to settle in.
