One challenge with keeping cephs have been with pest control. I have some aptasia in my tank that that I continually manually kill with kalk. However, this battle will never be won this way. Typically I would use peppermint shrimps to kill them, but obviously a shrimp wouldn't last more then a couple seconds after I introduce them to a tank with an army of cuttlefish. My question is. Does anyone know if a Sepia Bandensis will eat a Berghia Nudibranch? These nudibranchs will eat aptasia, but they are pricey and would not want to just throw that money into a nice ceph meal. I would guess that they wouldn't touch them, but does anyone know for sure?
