your squamosa is looking bleached...ive found that these indo blue squamosas are very sensitive to high intentisy led...suggest you move it further away from light...had it happen to a couple of mine and ultimately perished...now I keep my others firther away...have 6 of themMine continue to do well. My second Gigas is also doing well.
They seem pretty bullet proof to me. Mine has been ripped from its rock when I was careless siphoning, picked on by my regal angels, and has now been moved to a tank with sketchy water parameters and it still looks perfect.Has anyone lost a gig yet? It's ok, don't be shy, I am curious the survival rate as they seem tough.
