This is my first post - I'm new to all of this so please bear with me.
I would like to start a small aquarium and get a betta fish. I didn't want to jump into it without research first to make sure it's really something I want and can do... so, so far I have only purchased a small tank decoration to look at and keep me happy as I continue my research - LOL.
I have decided to get either a 10 or 20 gallon tank (probably a 10 to start with) and am looking at the Penguin Bio Wheel.
I know that this wheel hangs over the outside of the tank...... but, does that mean that it is only compatible with certain hoods? When I think of a hood, it's the standard black hood with a light so I can't imagine where this filter would fit and still have the hood on!
A silly question, I'm sure.. thanks to anyone who can explain this :)
