long story short the glass top smashed from my knifes fighting over food. and my ray seems to be going bananas, i vacuumed out like 30% of the white sand out, i even shut off all the tights and with a led flash light try to see the small left over peaces. thought it was all gone the other day. but today another spaz. also it happens when i feed him and then i can see like a little glass on him but idk what to do. i dnt want to keep stressing him.
