I have had my frog for a while and I have yet to see him eat. I do watch him for a good amount of the day, too. I have been putting in sinking shrimp pellets and freeze dried blood worms as well as the betta food and flake food for the other fish. Do you think he is just eating all of the old "crud" that is on the bottom of the tank? Also, he is really lazy. Is this typical? Don't get me wrong, when we moves, he moves FAST, but he doesn't move all that often...
