I boughta cleaner shrimp the other day and the guy threw a small shroom in the bag w/ it ( love that lfs) Anyway I cannot get it to hold it's too small to use a rubberband. Someone told me to use super glue gel but I thought it had to be stuck to a small rock and then glue the rock where you want it. long story short how do I make a very small shroom stay? TIA
