They are definately cuties! I was actually thinking about getting one when I get my 180 gallon. But decided against it. I'll just sit amongst the other and admirer them from a distance!
I was seriously consider them for my new setup. But the LFS told me they like a ph of 6.0 and very very soft water. Where I live its 7.2-7.4 from the tap and rather hard so keeping them would be too much of a chore. But they are awesome to look at.
