Rummy nose Swim bladder

[Fishfaced]

My rummy nose has been swimming with her head facing upwards for a couple of days now. Guessing it's swim bladder.
Should I put her out of her misery as she could be stressed and exhausted..?

Swimming difficulty is a symptom of several possible issues. It is actually quite rare as "swim bladder" itself. Internal protozoan, water issues (parameters (GH, KH, pH, temperature, and/or conditions such as ammonia/nitrite/nitrate), genetics can all include this symptom with or without other observable issues.

Consider all of these as best you can. Euthanization may or may not be warranted depending upon how bad it is.
