Huh... whaddya know! The thing I love about this hobby is how you can litterally learn something new about it after you think you know there is all there is to know haha!
I agree with Gemmy regarding the Elegance though... they are fragile and tough to keep happy... I don't think you want a clown bothering an Elegance IN ADDITION to all the other issues an Elegance has to put up with just to survive in a tank.
If you like Xenias then I say go for it!
Xenias have their own issues though but they're cool IMO and if you like them to put up with their downsides, then give it a shot! :D
