Well I did a little bit more research on it and found that it is actually quite common, pulled this from a guy who has propagated anemones for many years.
"Ours in the lab would occasionally get the bifid tentacles, but it seemed to be a transitory thing. They would look normal most of the time, develop the fork on a few tentacles, and then eventually one half of the forks would pinch off or otherwise disappear after a few weeks to a few months. They clones of those anemones didn't seem to form the forks any more than the previous generation, but it did seem more prevalent in the clones from the Waikiki Aquarium (a 10+ yr old line) than from other local sources."
Also saw that it may be from rapid growth or exposed to an excess of chemicals.(Not proven, just a theory.)
And thanks, also that'd be cool to see how similar or different the forked tentacles look, so post away ha!
