Great post !I just wanted to add that The weight of the tank rests on the feet of the stand.Like a women in spiked heels all the weight ends up on the point of the spiked heel.I am not sure of the weight of a 55 gal. tank is but it adds up after the water,gravel and rocks.I am referring to a steel stand,In a cabinet stand it would be distributed differently.Just keep this in mind when setting up the tank.I also agreed that I suggest to every one new to this hobby get a book and study all aspects of fish keeping.I too never add any fish to any tanks that I know do not belong in there.This also goes with anything else that they might think of putting in there like bottom materials,wood,rock, meds,fertilizers,plants and dirty hands.And if you are not sure just post the question.This place is great!Just my two cents.
