Wtf is "shimmying" (I know shibby, but shimmy???)Innes said:Taken from

"What if my fish 'yawns'?
Little is known about this behaviour, but in some cases it appears to be a response to poor water quality, so check ammonia, nitrite, and nitrate levels. Commonly only one or two fish yawn, sporadically, sometimes while shimmying. Both yawning and shimmying are often early warning signs of deteriorating environmental conditions.
Other factors which could be considerd are oxygen depletion and/or raised carbon dioxide levels; incorrect pH; chemical poisoning, including chlorine/chloramine."
