This is cometgirl using little peanut's account:
We've just had a good look at her this morning. She seems a bit more active, has no frayed fins, no red spots or raised or missing scales. The top of her head is usually translucent white, but today seems pinkish near her eye. She did seem a little boated a few days ago when she was also sluggish and bottom sitting. That is when I tried fasting her thinking it was a digestive problem. The bloating seems to have gone down now.
I have a hospital tank set up. I'll put her in there with aquarium salt, and order some metromeds.
