my anemone have become smaller

[Anartica]

the 31 january my anemone was about 15-20cm(se pitcure 1)
now it is about under 10 cm(se pitcure 2)
seens january i have moved it to a bigger aquarium with better light and water, it was in 50ppm nitrate for a while in first tank.
why is it smaller now? i want it big.

Just how they are. If you improved the lighting it doesn't need to stretch do far to collect light. Just feed it, it will expand or grow again
