My cat is fat. What is wrong with him/her?
Temp - 74 F
pH - 7.5
Ammonia - 0 ppm
Nitrites - 0 ppm
Nitrates - ~40 ppm
About Nitrates - I was out of town for a few days this week so I overfed them a little before I left, which I think is what made the nitrates rise... Regardless, the cory has been fat like this for a few weeks now. It is swimming normally but it does seem less active than usual. I do 40% water changes weekly and have plants in the tank.
I don't feed live foods and haven't added anything new to the tank. Tank has neon tetras and other cories. Also has a few snails as you can see in the photo... I cut down feeding but the swelling hasn't gone down. The other fish are not fat like this.
Thanks
