My worst has to be the Australian Arowana. I figures it would look cool to keep and silver and an australian together (like at the chinese food place by my house

) After thinking the whole thing out for a good 5 minutes, I figured hey I'm sure it won't make my life that much harder. The only problem was, was the size difference. The silver was ~6-7 inches and the australian ~3 inches, I figured they should be fine, and the aussie is just a baby so it will grow quick. Well moral of the story... Silver Arowanas are big, mean, hungry, nasty gluttons. But I still love him
Stupid Aussie cost me 30$
