Hi, I woke up and found my baby mandarin had a white patch of skin that looked like an ammonia burn and yes we are having an ammonia problem. It isnt super high but it’s been about 5 days and we are doing a %50 water change right now. She’s still swimming around pecking at her food. But she’s floating a lot. I’ll attach a picture but she’s floating and dragging her face across the glass. I am currently looking at a QT tank. It’s an 8 gallon tank. And my mandarin is less than an inch small. I would have to stock it with copepods and some small rocks right? Sand? No right? Please help me, I really want to save her. Please help me. Thank you soooooo much. I really hope she lives.i love her so much. Also if there is medicine to help the burn cure, than can I get some recommendations?
