Rodrick's fish

Rodrick's Fish was the fish of Rodrick that he got when Susan took the boys to buy a pet,Rodrick took the fish as it had the "agressive" label on it. When they got them they put them in the same aqarium.First of all it ate Manny's Goldfish,then it got a little fat. Then after that it attacked Greg's Angelfish and took of its eyeballs and ate it.Soon it ate the blind fish.After that the fish survived for two months,on the water's alage.Just then it started sleeping,Frank knew he wanted a dog so he fibbed to the whole family that Rodrick's fish died of natural causes and flushed it away in the toilet. If the fish was still alive after it was flushed,then it must be in the sewer or a lake.
