When I told them what it was, my family was a bit grossed out I think.

I siphoned the tank using an air tube (a bit painstaking, but it works),
and
found that it took the bubble nest out quite nicely. Just had to be
careful not
to bring it above the surface for more than a second or two. Little

didn't look pleased, however.
