Tankload of questions (long)

I love finding so many sources. It really helps to get whatever support you
need when you're starting out w/ something new (especially something that
could up and die on you if you screw up). So thanks.

It has to be something with this tank.

As you know, I picked up a juvenile maneguense to live for a couple of
months until everybody graduated to a bigger tank.

I come home tonight to find:

1. The heater is dead.
2. The water is at 74F (normally it is around 80F)
3. The managuense apparently followed the betta's lead. He's nowhere
to be found. I may have to start checking Sparky's hiding spots for
fishing poles.
