Total Newbie with an empty tank

[BullDog]

Thanks for the information all!

Piranhas definatly sound like something I'd like to have one day! Unfortunatly, it sounds like I don't have a proper habitat for them right now. I'll definatly look into them more if I ever upgrade my tank!

Canadbis - I'd love to have some of those, they're neat looking fish! Unfortunatly, I'm in BC, but if I'm ever in Calgary, I'll look you up

I was also suggested FW/brackish puffers, or cichlids. Puffers I would imagine are a bit more demanding on the care side, but how are cichlids? (How do you pronounce cichlids, anyhow? )
