I have heard pretty much everyone say that the Super Tongan Nassarius Snails (Nassarius Distortus) are reef safe. In this video I watch one not only eat a piece of food stuck in a zoanthids mouth but it also eats the top of the polyp off too! I don’t think these are quite as safe as everyone says they are. The 1st night after I put these in my tank I woke up to a very dead (previously very healthy) six line wrasse that had been eating frozen mysis and pods regularly and a dead and empty astrea snail shell. Tonight is the 2nd night so I went in with a red light to watch these snails and see what they are up to.
