smb, just a wild guess since the Jag hides alot now that he has tank mates but he's probably getting close to 4". He's not growing as fast as I had heard he would.
Mike, Big O has definately got loads of personality. He sees me and hes right at the top of the tank waiting for me to feed him. He eats right out of my hand and will nip at my hand if he knows I have blood worms or brine shrimp and won't just give it all to him. He's really cool!
