WOW have they grown, they look great man I finally got a living/eating solomon island!!! I found out the key was to not get them from.......... you know where lol
Yes they do host. And it was really just a matter of time before they paired up with it. At first my nem was tiny and it grew significantly and once it was a decent size and split multiple times the clowns just took to it.
How long have they been in the tank together? Im not really sure what their exact behaviors are when it comes to hosting, all I know is that it takes time and patience sometimes but they eventually find each other.
