I have a pair for over a year now, they even survived a move about two months ago. There are still no signs of blindness, or any other problems. They host in my bubbletips. They eat mysis, flake, brine, and pretty much anything else I give them, lol. I need to get some new pics up, but you can see older shots in my gallery.
I got them from Blue Zoo Aquatics after speaking with them two times at length. I think a lot of the survival has to do with handling before reaching the states- I know they are very susceptible to brookynella.
I haven't seen any available in a while, though.
