Our female ray isnt doing well. She's curling
She has been eating, but not enough to keep her fat. I have a male retic in the same tank that is very fat and healthy. The nitrates are less than 20ppm ammonia and nitrites are 0.
We're doing a large water change, but is there anything else that I can do?
She's been with us for a few weeks and was doing well, but today she took a turn for the worst. Every other fish in the tank is fine, and she ate a few bloodworms this morning (acted and looked fine too, just a little skinny). I got some blackworms, put them in with her and she wont touch them.
What should I try? Thanks in advance.
