your right, i should probably not buy one more fish untill i get a 20 gallon tank, i have to take responsability and clean it my self. but the reason why i was using fish is sometimes when i need to clean it the most i have junk all over my hands, didn't wanna mess up the chemicals in the tank. Also a big hand moving around the tank might stress the fish in the tank, good thing i don't have any ssemi-aggresive fish or my arm would have some scars to show!
as a begginer it would probably be an excuse for me not to do any work, i'll get right on it emediatly!
