Leopard has been in through 2 rounds of GC in the water followed by 14 days of copper and food soaked in GC. After 14 days moved her to an entirely new set up. That was 4 days ago. I’m trying to up her salinity by topping off with salt water before putting her in the display. Came home today to find her breathing heavy but still eating and swimming actively when I approach the tank. Lights went out and rather than burying herself she is laying on the sand bed breathing heavy. She not overly fond of this sand bed it seems to be very compact and she has difficult time burying herself. Worried I missed something. Any thoughts?
