used to be able to, now he has another tank on the right side that is another very large tank and on the left side he's got a shallow frag tank about 5' x 4'. He let the coraline grow up on the left wall so thick you can't see through it as a backdrop for the frag tank.
But you can walk on the front and rear of the tank.
You can't see it real well in the video but those locklines that come out to the left of the center overflow actually swing back and forth from left to right.
I love his tangs, they are very freindley camera hogs
