I have two german blue rams and I notice that they are not getting fed as of recent and when the flakes reach the bottom they spit them out. They don't like the new life therma A sinking pellets either. I notice one of them has become aggressive towards some of my platys when they swim down to the bottom. What foods should I feed them and what is the best way for them to get the food since they swim at the bottom? I know from reading around they can be hard fish to keep but I would definitely like to keep them.
