Hi! So I'm looking to get a UNS 60U (20 Gallons) as a big upgrade from my 5g Macro Algae Tank and am thinking about adding a Pearly Jawfish as kind of an "oddball" addition. From what I've seen, a lot of people say that a 20gal is acceptable since they mostly stay around their burrow unlike other species, would a 20gal be sufficient? Also, I'm moving a Pederson's Cleaner Shrimp over and would this guy be a snack for the jawfish? The Pederson's get between 1"-1 1/2" max and im worried that's snack size for a Pearly. Can anyone who owned / does own one chime in? Thanks
