From what I've seen online and at the shop, these guys hang out at the bottom. Mine is up at the top, has been since putting him in... staying in one particular area, about 4x4 inches, swimming a lot, kind of looks like he's "running in place" but with a bit more movement than that. What's up? Is this normal, is he stressed? Could there be a current there and that's messing him up? He hasn't gone down to the bottom to check out rocks, nothing... but otherwise appears to be ok..
thoughts?
