So I've noticed this big red bump about the size of a dime on the bottom of my males disc, all of the other rays are perfectly fine showing no signs of this. He's eating normal no signs of stress water params are normal, maybe I'm missing something what do you guys think it could be ? It's not a heater burn, not heaters in the tank and I'm running 80gpd drip
