I currently have a 29 gallon tank with a sand bottom, so i'm getting MTS's to stir it up and keep those anearobic pockets out of it, but i'm worried that the 3 yoyo loaches will completely kill off all of my snails. Do you think that the 25 snails i am getting will multiply quick enough to keep my yoyo's in check? i hope the sand also helps hide them a bit.
