Hmm.....I think probably 3-4 males would do for the guppies
For the Dwarf Gourami(or Powder Blue, both are very pretty, personable, and get about the same size)almost all sold in pet stores are males, though with just one, no, it wouldn't matter then gender
I feed bloodworms once a week(usually on WC days)and I also feed frozen brine shrimp once a week. I feed twice per day with a couple different kinds of flake, some algae wafers and shrimp pellets for the guys at the bottom, and occasional freeze-dried stuff. Though some like to feed live foods more often, even daily. I think it depends on your preference, if you can afford it, and what kind of fish you have really.
Kay, I'll be sure to take a look at the new photos
I know what you mean, contemplating on what to add to my 50 for a little more movement or activeness
its looking a little empty...
