Yeah I can't seem to find a reason for it. She changed almost instantly and is still this bright orange! Both of my Goldens are in that tank but they are acting fine and eating and everything. The bottom lining of them is orange as well. I can update with more pictures tomorrow to show how there has been no change. I am very mind boggled by this lol my blues and ivory have no changed at all so I'm confused by these Goldens hahaWell, that's a new one! If she started out a very light translucent yellow, is it possible that she somehow "flushed" the same way that a blush works in humans, or ammonia burns in fish? It really does almost look like her skin became redder underneath the shell. I'll be following this thread, curious to see what happens! Don't know how your snail suddenly became highlighter orange.
