None, lol. There will be no sand sifting gobies in my tanks. I’ve done that before and what a pain. If they aren’t covering corals they constantly sift the which adds tons of particles in water.Agree, highly doubt my V. Strigata will be allowed in my upgrade tank... He's buried LPS a couple of times
I'd consider something from the Cryptocentrus genus tho, as they rarely leave the sand surface before releasing the sand. They're much more static though, so might not be as useful for the sand sifting purpose.
@bubbaque which ones have you considered?
I will be the sand sifter. I have a long stick that’s like a spatula on the bottom that I will stir it up once a week with. I did it this morning and it took less than 5 minutes to do the whole tank.
