Hi, I have 2 fishes in a 35 gal tank - blood parrot and a red tailed shark. Both are 10 years old. Few weeks back, blood parrot was showing symptoms of swim bladder as she was swimming vertically with nose down. Based on suggestion from a nearby pet store, I did a couple of weeks food based treatment of Seachem kanaplex and Seachem focus. There have been couple of water changes as well since then. But now the blood parrot is staying practically near the top of the tank (picture below). She used to roam around and sleep inside the house but she is not moving from that spot now. She is still eating though. After eating, she goes back to that spot. When she tries to come down, her swimming pattern looks unstable and then she goes back there. Pls guide.
