Need help with an ID. I can't tell if this is an injury or something else.
Noticed one of my zebra danios hovering near the surface last night with clasped tail fins. Today his tail section appears to be red on both sides. It doesn't look like fin rot but I'm not sure. I did see some of the other danios chasing it around yesterday afternoon but I didn't think anything of it until seeing it today. It's also not interested in eating today even though it ate last night.
All others in the tank don't have any signs of the same thing.
Water params:
pH ~7.5
ammo/nitrite/nitrate 0/0/10
This is the best picture I could get. Any help is much appreciated!
Edit: Added water parameters
