get yourself 5 oscars, and 10 arowanas....
lol... you wont have room for water if you did...
actually, what you could do, is research like i did.. look at the fish guide and from there, decide which ones you like... then you can narrow it down further by seeing which ones are compatible with each other (difficulty of keeping, pH, water temp, agressiveness, etc)
why ask us which fish you should get? you have your own likes... not only would you feel better about picking out your own fish, but you'd learn a lot more if you just took the time to look at the fish profiles
