I finally got a lineatus, rhomboid, and pintail a couple weeks ago. The lineatus and rhomboid have been constant swimmers since the moment they were put in the tank. Beautiful fish. The pintail on the other hand seems to hide all day (at least from the time I get home from work). He'll come out and eat anytime I feed, but he just doesn't seem right. He kind of flutters/hovers diagonally the whole time he's going for food. He doesn't dart around like everyone else. Is this normal for a pintail? Like I said, I don't see him out at all to notice if he swims like that or just while feeding. Even after he eats he stays close to the bottom and drags his tail in the sand while he hovers around.
