Mold on Drosera adelae

See, I hate my D. adelae.  They're so fussy.  The only time I can get them to stay alive is when I keep them covered and forget about them.  I tried feeding one ground up betta pellets like I've done with other sundews, and this is what happened with my adelae.

Mold on Drosera adelae, after being fed ground betta pellets.

That leaf looks dried out.  I reckon I'll just snip it all off instead of trying to pull the mold off with tweezers.  I don't think that leaf's good for any photosynthesis anymore.
