I am sorry to break it to you, but most fish NEED a group of 4-5 or more to feel secure and safe. Fish that require schools do so not because it's pretty, but because without the security of a larger group, they are always stressed and more prone to be sick and catch diseases. By going out and getting one or two of whatever fish you like, you are ignoring their minimal care. If you cannot provide them with the minimum, don't buy them please! Besides, fish that are happy and healthy cost less in the long run AND they are so much more fun to watch. Trust me, please.
Guppies breed like guppies lol 5 will turn into MANY in no time :)
Also, my LPS agree's with me on the fact that Danios may be a hardy first time fish, but they need groups of 6 or more AND they are not a peacefully fish. They are fin nippers and hyper and need at least 24" long tanks for swimming. I have three, one of them is upsetting my WHOLE tank! Savage little thing! I plan on getting more, but my LPS is out of them, and I lost the 3 I bought 2 weeks ago.
Rules of thumb for tropical tanks... 1" of fish per gallon. Find out what the fish's max size is at adulthood. 2" fish would be 5 MAX in a 10gal tank. But use caution, a 10" fish would not be happy in a 10gal tank alone :)
Personally, the lists you posted are just a bit overstocked. You will have stress, disease and ammonia issues. Do your homework and fish keeping will be rewarding :)
