Yellow tang choking?

[rcmike]

Hey guys,

I have a yellow tang that I have had for a few months and occasionally he does something wierd at feeding time. He will start swimming erraticly and bump into things after eating. He then lies on the bottom or against a rock for a few seconds to a few minutes and the coughs out some food. After a few more seconds he starts swimming again. Is it possible he is choking? I managed to catch it on video a few minutes ago. Excuse the dirty glass and frags on the bottom. Been a little busy the last few days.

I believe it sees its reflection on the bottom/sides. The movement the tang is making appears to be a territorial gesture.

Sometimes it runs into rocks, the bottom, or whatever. I have seen it darting into rocks and then lay down flat on the bottom twitching until it coughed out the food.
