I have an Australian rainbow fish that for almost the past month has been having major swimming issues. Constantly swims at a very tilted angle (at times almost completely vertical) while jerking the whole body side to side. Also seems to have trouble maintaining depth (sinks when not swimming) so I'm certain it's a bladder issue. Still eats and defecates fine but the poor thing is clearly having a hard time so I'm looking for advice on if there's anything I can do.
Here's a pic (tried to get a video but I've been having uploading problems) compared to another rainbow swimming normally.
