Full moons and negative thinking does it, too. I recently wrote about a red
wendt I'd completely forgotten ever having had that spontaneously
remanifested itself in the middle of a clump of sags.

Crypts are infamous for dying off and then growing back. Generally, it's
a
change in the tank that causes it. Transplanting, pruning, a change in
water
parameters, etc., and the crypts might melt. Leave them alone, and they
always
come back.
