Been there done that, just makes a mess and screws with your water quality. I would try raw shrimp my knife loves it whole, and I break up pieces for my four-line and my chaca cat, they eat untill their bellys burst!!!
Sounds good. I won't use it anymore then. I put in a little the other day and my rtcXtsn loved it. None of my other fish would touch it. And man, did it stink up my kitchen...No mas...
