I've heard of using another tanks filter media... i just never really got how to do that.... sorry for such a long post
This is not a long post, pumh...I
write long posts.
As someone mentioned, if you intend plants, that's the quickest. As long as there are sufficient plants to balance the fish, the tank can be set up and will "cycle itself" when the first fish are added. Plant all the plants you can get and want, and the day after add a few small fish that you want. You can have quite a few, but to be safe as this is your first time doing this I would play it safe.
The reason this works is because plants use the ammonia/ammonium as their nitrogen which is a macro-nutrient. They are so good at this, they outcompete the nitrosomonas bacteria. The nitrifying bacteria in a well-planted tank are fewer than in the same tank without plants for this reason. I have never had ammonia or nitrite above zero in any of my tanks when I set them up, and I've been doing this for 15 years.
Of the fish you mention, don't use the rams, they are very susceptible to fluctuating water and should only be added to an established tank (2-3 months). The rasbora would work, or the tetras probably but not ones like cardinals or rummynose, they are also sensitive like the rams. Anyway, I would only have one group of either in with a pair of rams, and perhaps a trio of corys or a single catfish for the bottom. I would not overload a 10g with the rams and two groups of shoaling fish. Either the rasbora or a suitable tetra, 6 of whichever, once it is planted. Then after 2 months, the pair of rams.
