Its tough to say....the ray was past the fragile stage in growth, water is said to be good, and had no sores or marks on it...I assume it was eating fine....I guess sometimes **** happens....It s tough loss to hear any ray die.....

Pleco's should not be in the same tank as rays due to the plecos having rough mouths and love to suck on anything, even a ray, and it will cause damage and open sores which could lead to an infection....That might be the cause of death...post pictures if you have any of it to show what might of happened....a photo CSI case....
