About 11" the thing with angels and rays is I say 90% of the time the angel will become a snack just because 1. the body shape. 2. There not fast. The angel has a large flat body and pretty slow swimmers there very easy for the ray to pin the angel to the glass then it's bye bye for the angel. Doesn't matter how much you feed your ray. There metabolism is so quick with in two hours there blowing sand looking for food.
