Evidently hydra, planaria, and the like were more of a problem in Innes'
day when filtration was fairly primitive. I remember I had one tank
(containing an african lungfish) which became infested with a swarm of
swirling little bugs, some of which attached themselves to the fish. When
I looked a them under a dissecting scope they looked like little clams with
feet hanging out. Something jogged my memory and I opened one of my
various editions of Innes and there it was - Cypris. How often do you hear
of that one any more?
I say filtration was primitive, but I have some early, pristine copies of
"The Aquarium", and vendors are still hawking pretty much the same aquarium
gizmos today that they were 67 years ago.

A good way to threaten somebody is to light a stick of dynamite. Then you
call the guy and hold the burning fuse up to the phone. "Hear that?" you
say. "That's dynamite, baby."
