Sebae nem question

[caity]

So I got a sebae about 4 months ago and nursed it back to a healthy tan/brown. (It was bleached so I bought it on a discount in hopes I could bring it back) All the pictures I look of them they have longer tentacles but mine has always had short tentacles. Is this normal? Is it just because it is small 4"
They aren't exactly bulb shaped but look more similar to bubble tips than the sebaes I've looked up.
