My son wanted to get into the aquarium thing and found a lady who wanted to sell her 55 gallon aquarium, stand, filter, lights, hood and fish. All for just a $100. It had 8 fish. Two kinds of sharks, and some small Algea eaters, a tinfoil and 1 Red Belly Pacu. The Pacu is about 6 to 7 inches right now and starting to get aggressive. The lady didn't know what she was buying. I saw that these fish need a huge tank and would like to get rid of it before it hurts itself or others. I've checked with the zoo aquarium and some pet stores, so far no takers. I live in Indianapolis area. I'm looking for help or suggestions on what to do with it. Any help would be great.
