What Fish?

[Sang]

Hey guys! I just started up a beautiful 50 gallon long tank and can't decide which tropical fish I want to put in it. I want a unique basically bad ass mix of interesting fish. Would like if some of you guys can throw me some ideas of what all types of fish would do together without much problems. I want a good variety include crabs,frogs, crayfish, and smaller eels if you'd like. Thanks!! Looking forward to your ideas

well first you'll want to cycle that one.. i would advise to do a fishless cycle. (look on this site for more info on it)
and then you'll need to know if you are going to go for a community tank, semi-aggressive, or aggressive tank.
with that in mind, and once you have a set on what type of aggression you want, only then can you start picking out fish... 
so what type of aggression are you looking at?

I think he wants an aggressive tank setup?
But sorry to break it to ya Sang. Crabs, crayfish, frogs and eels are somethings that wont mix.
If you want a community you can do tetras. THey are wonderful fish. Maybe then you can have more complicated fish like the aggressive ones like cichlids
