How much and what kind of light do you have? How deep is the nem from the surface? How long have you had him?
Could be a light issue, but that trumpet seems to be doing ok. Do you feed the nem?
I have an AI sol. It sits about 9" below the surface. I've had it for about a month now.
I target feed every two weeks. It usually picks up a little bit when regular feed.
WooW..........below the surface??
That's why..........it's better to hang it above the surface.

HaHa. I asked him how far his nem was below the surface. I think that is what he meant my 9". At least I hope so. I have about 15 rbta's and based on yours reaching up like that, he may be trying to get more light. You could either try moving him closer or move your lighting a little closer. I wouldn't go any closer than 8" above the surface. If you can increase the intensity, try that.
Also regarding feeding, I feed mine a small piece of shrimp or silversides about the size of my thumb nail 2x per week. I don't think once every two weeks is enough.
