I bought a sand sifter Star the other day and it buried itself immediately. I was looking on the internet as to why and if it would resurface and I found a lot of discussion on that they are bad for some natural elements in your sand and will increase your nitrate level. Also that they will probably run out a food and die after some time unless you have a very large tank I was trying to see if I could get some clarification on this while I can still return him. Thanks again for any input.
