Help pruning a Thai Onion Bulb

I have a Crinum thaianum (Thai Onion Bulb) in my 30L fancy GF tank that's
growing like wildfire. I think it could really do with pruning, but I'm not
sure whether it's best to trim the ends of the leaves, or remove the whole
leaf from near the plant. The leaves that I've trimmed halfway up haven't
really grown since, should I fertilise now the plant's a few months old (in
my tank anyway)?

Mine does well too, and the substrate around it is always spotless

It seems to do pretty well on the fish waste without fertilizing but
you do what you think is best.

I was told (by the LFS and I dont know whether to trust this advice)
that if I trimmed the leaf the whole leaf would die off. I've not
found this to be the case - it's possibly happening very slowly
because the ends crinkle and die, but this is on very long leaves
(about 4ft long) and they always seem to get longer even if I take
the ends off.

Another solution is to try to wind them or persuade them to the
area in your tank where you would prefer them to be, but I don't
have much joy with this. It lasts an hour or two

I'm also having trouble finding more of this plant. I've not seen one in my
LFS since I bought it two months ago. It's growth characteristics would make
it ideal for our large planted tank at work.

I see it often in the LFSs in London, UK, so I can't believe it's
that hard to come by? But they grow so prolificly that for me, one
is plenty!
