Is this pearly jawfish a must have? I've seen videos but videos are videos. I have a fairly new setup with no sand yet and is planning to buy 90 lbs for my 30x30x30 JUST FOR THIS FISH. I would rather not have a dsb but I need an active bottom fish (gobies suck) so this jawfish seems to do the trick and seems gorgeous base off YouTube (never seen one at a lfs). Another words, is the jawfish worth $110 (90lbs sand/$90 + fish/$20?)?
