I’m looking for a hardy sand sifting Goby that will last. I’ve been hearing that sand sifting gobies tend not to last long because the sand bed gets cleaned and then it just wastes away. Is there any sand sifting gobies that are hardier than others? I’ve heard the sleeper head sifting goby tends to be a hardier one, but I wanted to confirm first. I own a 425 lXL RedSea tank; 112 gallons total. Thank you!
