I have heard that you should maybe not put in frogspawn with cephalopods due to them stinging. As far as I have researched and had success with for what you can have with cephs, and cuttlefish in particular, have been more along the lines of mushrooms and leathers. (as well as macroalgae)Dont know for sure just received a small video and some pics. Can you put a frogspawn frag in with them? Thanks
