New Spot on GloTetra

[homegirlashley]

Hi, I have had my Electric Green Tetra, which after doing some reading today, they are actually X-Ray Pristella Green Tetras, for about 6 months now. However, one of them has a new, much brighter than the rest of body, spot on it. I can't find anything about it. But I also during my discovery of them being X-Rays, see that it might be normal? But it didn't have it before so any advice? All of my levels are fine.

If it's just a spot, that has to do with the genetics of the fish so not really anything to do with it. If it turns out to be a bump, that's a different story. Bumps can be an internal parasite trying to leave the body or the beginning of a tumor. There are things you can do for parasites but nothing you can do for tumors.
