She would be close to full grown, they stay much smaller than cherry shrimp only getting to around 2-3 cm. Usually with the real dwarf shrimp keeping fish with them is bad, but spotted blue eyes are also small and the shrimp populations and blue eye populations both seem to be doing well in their dedicated tank. It probabaly also helps that in the tank there is a HUGE hollow log that the shrimp all hide and feed in, as well as a tangle of plants that the blue eyes spawn in.
