ok I have had about 12 rosey's in my 10 gallon for a week and bought some new ones to replace them so i can see if they have anything. So I but 12 roseys in the tank and within 1hr they are down to 3 I have seen my biggest senegal eat atleast 6 of them. Now this morning he has regurgitated atleast 3 why is this, my other 2 poly's have not done this and i notice this same poly do this about 2 months ago with massivor delights. His belly still looks full which makes me believe that he has had more then six. I have feed them these fish in hopes to vary there diet once every couple months, and i change what i feed. 2 months ago it was earth worms.
