I bought a Betta from Petco three days ago...he's on a hunger strike. Offered him freeze dried bloodworms after 8 hours in the tank; he pulled one it and spit it out. The remains went to the bottom. Offered him frozen brine shrimp and freeze dried bloodworms yesterday and today, not interested... He's active and looks good. Seems to ignore the mystery snail. Seems like he's almost always on the move...top to bottom, popping bubble from the aerator. It looked like he might have acknowledged my presence for the first time a few minutes ago...seemed to be staring at me.
