I've had my little Blood Parrot Rusty for over a year now. He's always been spunky and energetic. Last night, I noticed him hanging out at the bottom with his dorsal fin folded in, almost leaning against the tank wall. He will sit there with his body angled downward. Normally when I come near the tank, he comes right over, does a "feed me" dance, and just watches what I'm doing. Yesterday, he noticed me, but didn't come over. Eventually, I got him to move around some by swapping sides of the tank, but he wasn't his usual energetic self.
