I think you just got those picasso's not too long ago going by memory.
If the hadonni is doing well, just be patient, or do as Todd mentioned and maybe pull the elegance(those are normally a bit of a challenge to keep themselves)
I say Sebae/crispa because I've seen so many inexperienced people able to keep them compared to carpets/hadonni's.
I've seen tanks fry/crash and all that survived was the crispa a number of times.
But they get huge.
Every LTA I've had was very sensitive to light/flow/movement of any kind, a snail falling could make it suck up tight to nearly nothing.
Personally, I'm extremely happy w/ my Malu, seems perfect for me anyway, stays at sand bed, and relatively small at 8-10"
My sebae/crispa got to two feet in diameter, and LTA at 18", just took up too much space in a mixed reef for me.
