If you culd have any kind of fish what kind woud you have in your aquarium?

I would choose KOI since its the newest aquarium specie. I would also consider shark. One of our neighbors have it and I find it cool. I won't anymore choose gold fish because it kinda common.

A few years ago, I was reading an article on this guy-he might've been a marine biologist or something like that, can't remember. But he kept an octopus in an aquarium. They don't live very long-I think only a year or two, and can be quite tricky to keep-they love to crawl and escape, plus you have to make sure it doesn't ink or do a water change soon after it does, but it sounded like it was really personable and friendly. Ever since I read that, I've wanted to try to keep one....one day :)

I would have catfish, as love to watch my daughters catfish play. I purchased aquarium toys for their tank. Now they are playing every night including pushing blocks across the bridge and yesterday it was queen of the bridge, which one of the females kept pushing everyone else off of her place.

I would have a hammer-head shark. I think they are SO cool!

i would have a glod fish, they are the most inteligent of them......
