Hello! I am a new 55 gallon aquarium owner. I have one blood parrot cichlid but I rarely see him because he hides in the very top of my castle all day long. If he comes out, the moment he sees me, he will take off running back into the castle. Recently I have noticed that he will come out and start doing this weird thing where he is like puffing up his cheeks and blowing out hard at the glass, while shaking his body. (I have a video of it but I don’t think I can post it on this forum.) When he does this, he’ll do it for like 10 minutes straight. Any ideas what is going on with him?
