I thought I would mention this as I often get asked this question. You may notice your Oscar twitching occasionally. Don't worry too much about it, Oscars seem to do it occasionally. Don't ask me why, I couldn't tell you. I would imagine it's something to do with their nervous system. Mine often do it when they are cleaning rocks and shovelling substrate. You may also notice their tails quivering. This is also nothing to be concerned about. My female Oscar does it when the male touches her. Again, there is probably some scientific reason why they do it and I'm sure that someone knows. As long as you know there is nothing wrong, that's all that matters

I may not always be right, but I am always the BOSS :-)

FYI this is often mating gesture as well as sign of aggression

Yes, quite possible as my female Oscar does occasionally when the male touches her luckily, I've never had an aggression problem with my Oscars .
