This is the first time I have ghost shrimp and want to make sure I am feeding them enough. I have two in a 5g tank with my betta so they do not get to eat any leftover food because I feed my betta pellets and he eats them all. What I have been doing is feeding them one sinking shrimp pellet every other day. Is this too little or too much? I cannot really see if they eat it all or not because they carry it around the tank and sooner or later, I don't know where they left it. And then it is hard for me to find because it blends well with my sand color gravel.
