Yep, anenome are a real estate hog, combine with the finicky attitude that they have and horrible shipping, its hard to get a good one from a LFS.
Why sebae?........I have had a few anenome, in fact tried another "rose" recently and they just seem to be heartier, always open, don't move (I had my last one for a year and it only moved once and only due to an alk spike.)
IMO rose anenome are overpriced and overhyped, most I have seen have been sick,weak, or not even true roses.......which can command a high price. Enflate, deflate and most don't keep the "bubbles" which is said to be a sign of stress.....so they end up looking like LTAs anyway..........
I had my big Sebae in with my SPS for the longest time.....now that was daring, and I was the same didn't dare rearange it...
Anenome do command most of the tank and the clown(s) in them are very territorial......I got tired of having half the tank dedicated to it so I got a nano........because the sucker got too big (18-24") I tried the new propogation technique a few months back of cutting them.....didn't work out, I ended up slicing a $200 anenome in two and killing it.......but you break a few eggs in making an omlet and if propogation techniques like that can be perfected we can be self sustaining......but I digress.....
I have a large maroon clown so a cream colored with blue/purple tipped sebae was a nice contrast.....
Even though I debated getting another anenome recently was able to pair the large female up.......so another Sebae was just purchased yesterday.......a little sick and stressed, but already has latched in and hopefully grow big and strong. It with the happy couple should be fun to watch..........(ok, ok, I lie....the girlfriend was mad at me for cutting up the other one, so I got her another.....I was thinking about ditching the female maroon and getting a cool dwarf angel and some zoas and calling it a day......)
