Tiger barb stayingVertical

[nickn313]

one of my tiger barbs lies vertical at times...and gets back to normal swimming... its really strange..he swims around a little and then stays vertical...nose down... wat does this mean? he doesnt seem to have any other problem...swims around, easts well, looks healthy..

He could be sleeping. That is normal tiger behavior. When one of the tigers want to be king of the tank, the submissive ones will do that a lot.

Tigers seem to all do this from time to time.Mine do.
