Sick Female Sword

[frankfair]

I have a pair of pineapple swords in my 26 gal bowfront. The female seems to be doing a slower version of the twist (that's a dance for all you youngsters) when she is not swimming. Her whole body just waves back and forth from head to tale as she hovers in the water. She swims fine and eats good. She seems to appear normal except her tail fin may be not spread out as much as it maybe should be but not clamped.

All other fish seem healthy including Pygmy cats, neons, mollys, zebras and barbs.

Is this normal for some fish? Should I do something other than watch for further developments?
Thanks

I don't know what's going on, but I am bumping this. Sorry no one has been here to help you yet.

I think it may be to say "Ok this is my spot dont come here" Its basiclly marking territory. I think so

I don't think that sounds normal. Keep an on eye on things and watch that no fins are clamped.

As a preventive measure I would do a couple extra water changes. It could be stressed if it's fins are clamped and water changes will help boost it's immune system.
