Does anyone have experience with Rainbow Sharks acting weird? My guy William Sharkspear likes to wedge himself vertically, head up, between the glass and a plant. Every time I try to take a picture or go near him he easily moves to the front of the tank to greet me, but the weird position is mildly freaking me out. The rest of the time he swims normally but seems to love resting in that position? My tetras in the tank are acting normally and the water parameters are right on point so I have no idea why he’s doing this. Any help is appreciated!!
