my brother gave me a 29 gallon aquarium and i am in the process of setting it up, i got the filter and gravel today at work. while the tank is cycling i am trying to decide what type of fish i want.

i would like to do semi-aggressive, but i dont know if i have enough room, i really like the dwarf guoramis we have at work. i could do tropical community... any suggestions? i am the "fish guy" (and small animal/bird/reptile) at work (one of them at least), but i dont know what i want to do with MY tank, so any and all suggestions would be appreciated
