Just an update, well the harleys are now eating the peices of sand sifting starfish but I have to protect them from the CBB who wants to steal the peice from them. I've looked around on the net and have not found any info on CBB's eating starfish. Weird I say. I chase the CBB away with my tool that I pick stuff out of my tank with until the harleys pack the peice to a safe eating place.
