Doesn't look any smaller (or much different) than what was sold to me as Shufeldtii. Mine vary in colour from a light sand to a dark bluey/grey. Some have no markings- some have spots and blotches throughout their bodies. A few of mine grow a little larger than a female cherry shrimp- but not much larger. They're quarellsome but the remind me of pitbulls with foam teeth. They bicker- but I've never seen them cause any harm to even the smallest shrimplet.
I'd be surprised if most dwarf Crays in the hobby don't have a littly hybrid in them though- it sounds like Camberellus species all readily hybridize.
