My son has been bothering me for over a year to get one of these, but he had his 10 gal tank filled with fish. He finally talked my wife in putting all his fish in her tank and to empty his. This was a suprise for me just before leaving on vacation. Also for his B-day he got a gift cert. for a local pet store (my wife I think is working against me). So after a long week of vacation and him bugging me the entire trip, we got one.
