I am located in Wheeling IL The larger one is approximately 5" and the smaller one is approximately 4-4.5"
They are tigerfish so naturally they are semi-aggressive right now when they are young. They have killed a few tank mates (bala shark, etc, nothing very aggressive) They need tons of flow in the aquarium and can be very jumpy if you walk up to the tank too fast. But awesome fish that are built for speed and they get awesome teeth when they get older.
