I'm trying to find some information on this little guy, I know his name but I can't seem to find any websites with a decent amount of general information. What little tidbits I've found are that they can grow to up to 23 cm(9 inches) which means he'll have to be sold, but I want to know if he would be okay around my other fish in the tank. He's been showing some aggression to my cories, I'd just like to know a little more about him.
