I hear you. I have tried and I will try again sometime. Right now oscars are growing so fast it's scaring me.My bass was initially that way, until it realized it wasn't getting anything else and that everyone else was going bat ****z over the pellets. Now it's the first to demand to be fed, and will tail slap everyone else near by because it's so eager to be fed anything.
Let then starve for a bit and they won't be picky.
