I was away for a few days (three) to see a friend who just had a baby and I left my sister to care for my betta. The second day we were in the city (far far away...) she said that he was eating and that he was fine when before he didn't eat.
Anyway, I get home, and there's a pellet of food in the tank uneaten, and he's hiding in the fake plants. (I can't see him, (and think he's dead because my sister was taking care of him and she's the type to just throw away a dead fish and not tell anyone about it until they find out themselves. But she did care for him) so I reach in and I accidentally scare him out of his plants.
Then when he's there, he sinks to the bottom (but not quite all the way, he's not resting in the gravel or anything) and he just sits there.
Okay, on to the gill issue. His gills are up, (or at least not resting in place) and his airways are working really hard, just opening and closing, (they're pretty big too) When his gills move his mouth opens a little too. He's not bloated that I can tell, and he doesn't have white dots on him, but he's changed from blue to a kind of blue-pink on his body and his GILLS ARE HUGE. :'O
