Don't do it. I've lost 4 in the last year. All carpet surfing. I have a clear view lid on my reefer 625 and the IM lids on my IM tanks have 2 of those. They always seem to find a way to jump out. I've moved on to Nasarius snails and conchs for keeping the sand bed clean. They put in work are interesting to watch.I just purchased a diamond goby 2 weeks ago. I had a makeshift lid on my tank while I'm waiting for mine to be built and shipped. He still found a way to get out and I woke up to him dried up on the floor. I'm debating on getting another one when I receive my lid. Does anyone know of a better sand sifter that won't bother my corals?
