So as I was feeding my fish this morning and noticed one of my corys had like cuts on it side. Can't really figure out how he did this or if he is sick. I ran a test on the water and the parameters where fine at 0 ammo and trites and 5 trates if that. I did a 50pwc just incase but not sure what else I can do for him. Here are some photos I took with my phone to see if anyone can help.
