The camera was having a hard time focusing through the glass. I don't see any pinecone scales though, you can kind of see in the photos, but all of her scales are flat.

No idea what it is or how it got there, but I'm always removing some and moving it around, it seems to do great!
If she laid her eggs in here, would it help protect them from the other fish? I could either place her in there within the fish tank and let her spawn, or I could place it low enough so that she could swim in and lay her eggs there if she wanted? Either way I would surround it with lots of live and fake plants. Not sure if its good or not, just something I came across on
