ok ok, i feel a bit of a dumbass now. been talking to somebody who knows rays and although it might go well for a while, the risk is still there. i really wanted a ray but i should put my own feelings aside for now and think about the fish. i do not want any fish to harm the other so im follow your advice too and dont do it.i feel silly as i really wanted it but fish health is more important than my own needs. gotta take care of what i already own.
thanks for all replies guys.
