Yeah, I had a GBTA for three years, I sold it to see if the clowns would turn. Two months later and no luck. There was a thread I had posted on about it awhile ago but I lost track of it.
Either way, I didn't like my tank without an anemone and I got a great deal on this rose so I picked it up. My clowns are happy and I guess I really don't care if they get all black. I'm still crossing my fingers though, some people have RodOnyx with BTA's that have no problem, maybe this BTA is different? Maybe a difference w/ rose and green or maybe no difference at all.
Who knows!?
