Hello everyone. Had a quick question on my oscars behavior. I have 3 oscars in a 180 gallon tank. Lately one of them is moving alot of gravel and looks to be making a clearing. and hovering over the spot not letting the others near it. Sometimes when its near the bottom its head starts twitching a little and it circles around the clearing more than not. Is this fish looking to drop eggs? or am i just getting my hopes up
