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.
These parasites does not cross infected. Snails parasites will not infect clams IME. Had problem with the snails parasites in the past.I have a potential issue in my tank: suspected pyramidellid snails on my turbo snails. I have examined my gigas pretty thoroughly for them with no evidence of their existence on the outside of the clam. I've never seen these before in my system and haven't added anything other than the clam, which I got in a sealed ORA shipping bag that rules out my LFS as a possible source. I suppose it is possible I never saw them in my 150, but I'm posting this to encourage folks to QT their new arrivals just in case. Pyramidellid snails are super easy to deal with if you know you have them.
