I've had this pair of clowns for just a month or so and decided to get a BTA. On Sunday I got the BTA in the tank and on Tuesday evening the onyx picasso started hosting! Sorry about the blue pics, this was just after it started hosting, main lights are off. The BTA is purple with green tips and the clown rarely leaves it anymore! So excited! The snowflake hasn't really gone in the nem, which is fine because it was being quite aggressive with the onyx and has left it alone since then. I'm guessing eventually it will host too, but who knows.
