I'm planning on getting some guppies.  The aquarium they are going to be in is the baby biorb aquarium.  It is four gallons and I would like to know how many guppies would fit in this tank.

Thanks,

QUESTION: Thanks
I also have some other questions.
Is it alright to have two or three males together?
and
Do I clean the tank fully (as in empty it out, scrub and add water) every week?

Answer
Hi Sara,
 Two males shouldn't be too much of a problem, though you never know for sure.

 In general, you never scrub out a fish tank.  Scrubbing it out kills all the good bacteria
as well as the bad and is essentially like starting the aquarium again from scratch.  You are MUCH better to change 25% of the water once a week.
