I have a 150 5-2-2 with a 4 inch dovii in it. When the dovii gets a little older (big enough to not get eaten) i'm looking into getting a motoro stingray with him? I'm very new to ray keeping so I have no idea if this will work out. Trust me, I know that my dovii will be very aggressive but I'm not sure with a ray. Will they be ok with each other or just forget about it? Thanks.
