I purchased a bartletts anthias 2 weeks ago, and it has layed on the bottom the entire time. I purchased two others at the same time and they act normal and swim normal. This fish looks completely healthy, good color. I called Live aquaria and asked them, and they said to fee it a green pea for swim bladder problem, which I did last week, but the fish hasnt changed behavior. they recommended I post here to see if anyone has any experience with an anthias acting like this? When I feed the tank it will swim up into the column, and then goes right back down and rests on the bottom. HELP
