Welcome to the fish keeping world.
Your 'glo-fish' appear to be Zebra Danios. Normally, there is the standard blue, and the albino version. These are one of the fishes on the market that are a part of the dye/color enhancement craze. Hardy, schooling fish that love to zip around the tank.
In addition to telling male and female guppies apart, you can sex all livebearers (guppies, mollies, swords, plattys) by the anal fin. Females have a full lobe fin that hangs down when they extend it. Males have a barb like fin that they keep tucked up against their bottom. Compare the anal fin of your sword to the male guppies, and you'll see they are the same. Now compare to the female guppies.
Your glo-fish are egg layers, and not able to be sexed in this manner. Many egg layers are diffficult to sex. Female danios are typically larger and plumper. Having only 2 wont be a great sample size for comparison.
The danios and the sword will devour guppy babies too.
The underground filter "cleans" the water by making the gravel the biological filter bed. As your tank cycles thru the nitrogen cycle, the beneficial bacteria will form colonies within the gravel, filtering out ammonia and nitrites from the water. Dont remove the gravel for washing, or stir it up. Use a gravel siphon to do your partial water changes and remove excess detritus from the gravel. Ask your local aquarium shop for a demo if you are not yet familiar with the siphoning process.
Bottom feeding cats (Corydoras aka Corys) will love to eat the excess fish food that falls to the bottom. But, i am a firm believer that they and other cats dont eat fish poop or other crud, thus 'cleaning' the bottom. I worked in a fish shop for many years, caring for and raising just about every type of fish on the market. Catfish are very aggressive eaters of fishes and fish foods Feed catfish correctly.
Enjoy your fish!
