LTA tentacles shriveled?

[Hoodstream]

So I got a LTA recently and since I got him he’s been really chunky and I noticed some tentacles were shriveled when I bought him but I’m curious is this cause for concern? Should they have come back by now? Is this permanent?

They may shrink due to insufficient lighting. These corals utilize light for their cells and production of building blocks for energy known as zooxanthellae and needs adequate light to accomplish this
High water flow would be another cause
