Navfish
Fish Fanatic
Update: He's now been on general cure for a couple days and he is much more active and responsive. Whenever I tap my finger on the lid, he immediately comes up and stares at the top of the tank, waiting for food. While he doesn't fully eat the flakes, he eats them and then spits them out (then repeats them). This is good because he would usually ignore it a couple weeks ago!
