Glad to hear you are doing well.
There are folks out there that have had "success/survival" in mixing anemones, but I am not aware of enough examples to claim it works.
In fact, I was able to tell over time, my mixing attempts really introduced some level of competition or differing in preferred environments. Part of the reason I reduced my stock so much, just too much trouble maintaining dozens of separate systems.
At this stage, I have 3prs breeding and a couple of anemone species....actually looking to downsize a bit more but cant seem to part with any of my long term friends. If I get my act together, I may come begging for one of your Magnificas this fall for a project :>)
Cheers.
