That's hilarious he lets you get that close without freaking out. I'm convinced mine would bite the crap out of me before I got anywhere close to being able to touch him.
Not sure which one you've got here, but it is extremely nice looking. I don't know if lacs get their distinctive head shape only when larger, but this one doesn't seem to have the slope on the top like I would expect. I haven't seen enough intermedius or australis to be able to ID them by sight yet. I would have jumped on this one regardless though, nice looking fish.
