Very beautiful! The anemone looks super healthy! In my personal opinion, bubbled tips are a lot prettier than just straight tentacles. If you got that from a LFS, it was probably bubbled due to stress, and now that it is settled into your tank it is happier. Another idea is that clownfish sometimes cause the anemone to loose their bubbled tips, but nobody knows what causes it for sure. Just remember to feed it a few pieces of mysis every 2 weeks, because it is better to feed them less than more. Anemones normally use up all the energy or more from the food by digesting it, so small pieces of food in small amounts every few weeks is best. What kind of lighting do you have it under? Here are a few things that play roles in bubbled or non-bubbled tentacles. Nobody knows what to do to keep them bubbled or straight.
1. Water quality
2. Lighting
3. Stress
4. Hosting
5. Feeding
6. Splitting
7. Injury
And a lot more. It does not concern the anemone's healthy if the tentacles are bubbled or not, so don't worry. The anemone looks great to me.
