I've noticed that I have to sneak up on the tank and not get too close
if I want to observe them. :-)

Lots of fish will hide if there are no other fish in the tank, that is
why alot of cichlids require dither fish. When they see the other fish
swimming around, they know it is safe to come out of hiding.
My electric yellow labs were hiding allot when I first got them, as soon
as I added some rainbow fish they came out and are all over the tank.

It occurred to me that this might be partly a lack-of-dither-fish
effect. We're going to have other fish with them soon, but we need to
get our mid-sized 80 first, and then this 20 will be a quarantine tank
in the short term.
